Product Introduction
What Is 316 Stainless Plate?
Grade 316 stainless steel plate is the standard molybdenum-bearing grade of stainless steel plate. The molybdenum gives 316 stainless steel plate better overall corrosion resistant properties than grade 304 stainless steel plate. It has particularly higher resistance to pitting and crevice corrosion in chloride environments. 316 stainless steel plate has excellent forming and welding characteristics. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. Grade 316 stainless steel plate also has outstanding welding characteristics. Grade 316L stainless steel plate is the low carbon version of 316 stainless steel plate and is extensively used in heavy gauge welded components.
Excellent corrosion resistance
316 stainless steel plates are popular among manufacturers because of their remarkable corrosion resistance. These plates have a unique composition that comprises molybdenum, which enhances the material’s corrosion resistance to various chemicals and harsh environments. They can withstand exposure to salty seawater, acid solutions, and chlorides, making them suitable for marine, chemical, and processing industries.
High-temperature resistance
The high-temperature resistance of 316 ss plates is unmatched. Unlike other grades of stainless steel plates that tend to fail or deform under high temperatures, 316 retain their shape and strength, even when exposed to high-temperature applications. They can withstand temperatures up to 1500 degrees fahrenheit, making them suitable for various high-temperature applications.
Durability and strength
Stainless steel 316 plates are also known for their high durability and strength. They are relatively robust and resistant to wear and tear, making them ideal for applications requiring exceptional strength and resistance to heavy mechanical loads. Additionally, the material can withstand impact and shock, making it ideal for use in applications requiring high mechanical stress tolerance.
Aesthetic appeal
Another benefit of using ss 316 plates is their aesthetic appeal. These plates have a unique lustrous finish and are resistant to staining and corrosion, making them ideal for architectural and decorative applications. Their ability to retain their shine and elegance, even under harsh environmental conditions, makes them highly sought after by designers and architects.
Low maintenance requirements
316 stainless steel plates require minimal maintenance and can last many years without constant repairs or replacements. They are easy to clean and maintain, significantly reducing the long-term costs associated with their use. Additionally, the material is highly resistant to scratching and staining, making it easy to maintain and keep looking new for a long time.
Alloy 410S (UNS S41008) is a low carbon, non–hardening modification of Alloy 410 (UNS S41000) the general purpose 12% chromium martensitic stainless steel.
Alloy 347 is a stabilized, austenitic, chromium steel containing columbium which allows for the elimination of carbide precipitation, and, consequently, intergranualr corrosion.
Alloy 321 (UNS S32100) is a titanium stabilized austenitic stainless steel with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 – 1500°F (427 – 816°C).
AISI 904L stainless steel (UNS N08904) is a high alloy austenitic stainless steel. Compared with 316L, SS904L has lower carbon (C) content, higher chromium (Cr) content, and approximatively twice the nickel (Ni) and molybdenum (Mo) content of 316L,
Alloy 317L is a molybdenum containing, low carbon austenitic stainless steel with increased additions of chromium, nickel, and molybdenum for better corrosion resistance and increased resistance to chemical attack for sulfurous, acetic, formic, citric, and tartaric acids.
Alloy 304 a T-300 series stainless steel austenitic, which has a minimum of 18% chromium and 8% nickel. Type 304 has a maximum carbon of 0.07%. It is the standard “18/8 stainless” that is commonly found in pans and cooking tools.
Alloy 316/316L is molybdenum-bearing austenitic stainless steel. The higher nickel and molybdenum content in this grade allows it to demonstrate better overall corrosion resistant properties than 304, especially with regard to pitting and crevice corrosion in chloride environments.

316l
As of now, this is perhaps the most widely used variant compared to the standard and the 316ti grade. Originally, low carbon grades were more expensive and difficult to produce until the introduction of the production process known as argon oxygen decarburization (aod). This grade of stainless steel 316 has a lower carbon content to reduce the effects of sensitization.
316h
This grade contains higher amounts of carbon, improving its thermal stability and creep resistance. Its corrosion resistance is comparable to 316l. However, due to the high carbon content, it is prone to sensitization which makes welding joints vulnerable to corrosion.
316ti and 316cb
These are referred to as stabilized stainless steels. Instead of lowering the carbon content, titanium and niobium are added to reduce the effects of sensitization. Titanium and niobium are strong carbide and nitride formers, which helps prevent chromium from being consumed. Both grades have increased resistance to intergranular attack at the welded regions.
316n
This is a less popular grade of stainless steel 316 which has higher amounts of nitrogen. Nitrogen-rich stainless steels are usually considered highly alloyed, super austenitic grades in which higher amounts of chromium and molybdenum can be added. Alloying nitrogen in stainless steel 316 creates similar properties as adding more carbon, which results in improved hardness and higher strength.
316ln
This is a 316 variant with a lower carbon but higher nitrogen content. Similar to 316l, having a lower carbon content enables it to have better corrosion resistance in the welded condition. To compensate for the loss of carbon, the amount of nitrogen is increased to improve its mechanical properties.
Common Forms of 316 Stainless Steel
Sheet
If versatility is what you’re after, sheets of stainless steel are hard to beat. These large, flat surfaces are cold-rolled, and you can cut them into a variety of sizes, with widths ranging from 0.5 mm to 6 mm. You may look to this format for many items you’d find in the kitchen, like cookware, grills, sinks, countertops, and refrigerator, dishwasher, and freezer finishes. Xometry can laser or waterjet cut sheets of 316 stainless steel to create flat parts or patterns. You can learn more about this on our sheet cutting services page.
Bar
Bars are also known as rods, and you can find them in cylindrical or rectangular shapes in several different widths or diameters. This type of sae 316 stainless steel offers up the same properties as sheet metal, but bars can provide more strength and bear heavier loads. You’ll notice this kind of format in applications for construction and marine industries, and its finish is smoother and free of that well-known brushed texture found in homes. We often source bar stock when customers choose stainless steel for their cnc-machined parts.
Plate
Perhaps you like the idea of stainless steel sheets but require a thicker width. That’s where stainless steel plates come in handy as these are similar to the aforementioned format but come in widths of 6 mm or thicker. Unsurprisingly, this makes plates a great choice if you’re involved in industries that need chemical processing equipment, structural components for buildings, or pressure vessels. We can also machine plates or use waterjet cutting to cut them into various flat shapes.
Hot-rolled
This format of stainless steel comes from a process called hot rolling, in which you heat the material past the temperature point where it loses its crystalline structure and then reshape it and allow it to cool. This is great if you want stainless steel that can be formed and welded more easily. It’s more involved than other formats and moves molten steel from an argon oxygen decarburization vessel into a cooled continuous caster, where it’ll cool and solidify into a slab shape. You’ll find that the most popular applications for it are in the automotive, industrial equipment, and construction industries.
Cold drawn
The cold-drawn process (also known as cold working and cold rolling) works with stainless steel in a cooler environment than the broiling furnaces of hot-rolled, normally hovering around room temperature. They are normally in rod shape with smaller diameters, and you’d choose this style of processing if smooth finishes and hardness are vital to you. Precision components, shafts, and fasteners are a few kinds of products you could create from this format of 316 stainless steel.
Annealed
With annealed stainless steel, you’re putting it through an additional process to maintain its strength and formability while also boosting its corrosion resistance. It’s also called solution treatment steel and focuses on “resetting” or “relieving” the steel so it can be worked on and reshaped once more without cracking or breaking under pressure.
Types of 316 Stainless Plate
These are the most frequently used types of stainless steels. Austenitic stainless steels tend to have a high chromium content compared to other steel alloys, giving them a higher resistance to corrosion. Another common characteristic of austenitic stainless steel alloys is that they tend to be non-magnetic-though they may become magnetic after cold working.
The second most common form of stainless steel after austenitic alloys. As the name implies, ferritic stainless steel is magnetic. These alloys can be hardened through cold working. They also tend to be less expensive because of their reduced nickel content.
The least common category of stainless steel alloy. Their corrosion resistance tends to be lower than either ferritic or austenitic alloys, but they have a high hardness. Martensitic stainless steel alloys are often ideal for applications requiring extraordinarily high tensile strength and impact resistance. When said applications also require corrosion resistance, these alloys may be used with a protective polymer coating.
This category of stainless steel derives its name “duplex” from its composition; it is made of half austenite and half delta-ferrite. These stainless steel alloys have better corrosion resistance, especially against chloride pitting, and higher tensile strength than standard austenitic stainless steels. Due to their physical properties and chemical resistance, duplex stainless steels are used widely in the oil and gas industry for pipework systems or as pipelines and pressure vessels in the petrochemicals industry.
This category of stainless steel is comprised of durable, corrosion-resistant alloys with exceptional strength. They can be treated to yield strengths three to four times that of standard austenitic stainless steel. They are most commonly used in the aerospace, nuclear, and oil and gas industries.
Cost
The cost of stainless steel primarily hinges on the alloys incorporated into its composition. While all stainless steels necessitate a minimum of 10.5% chromium and are alloyed with a significant amount of iron, the presence of other elements plays a crucial role in shaping their properties and characteristics, consequently influencing the overall cost.
316 contains a minimum 2.0% molybdenum which makes it much more corrosion resistant than 304 however, as it is a more expensive element, generally makes 316 a more expensive grade of metal.
Magnetic properties
Both grades are austenitic, indicating they inherently lack magnetic properties. However, cold working can impact this characteristic. When stainless steel undergoes forming or cutting processes, there may be a slight enhancement in its magnetic properties, albeit minor.
Corrosion resistance
While both grades offer good corrosion resistance, stainless steel 316 surpasses 304 in environments containing chlorides, such as saltwater or coastal areas. The molybdenum content in 316 provides an extra layer of protection, making it more resistant to pitting and crevice corrosion in these challenging conditions.
Temperature resistance
Stainless steel 316 exhibits better resistance to high temperatures compared to 304. This is due to the presence of molybdenum, which enhances the alloy’s ability to withstand elevated temperatures without compromising its corrosion resistance. This makes 316 suitable for applications involving exposure to high heat.
Strength and durability
Both 316 and 304 are strong and durable stainless steel grades, but 316 has a slight edge in terms of strength. The addition of molybdenum contributes to higher tensile strength and improved overall durability, making stainless steel 316 more robust in demanding applications.

How to Maintain 316 Stainless Plate
Avoid abrasive sponges, pads, or cloths
First, let’s learn what not to do. The number one rule of stainless steel maintenance is to steer clear of abrasive sponges, pads, or cloths. These rough materials can scratch your precious stainless steel, leaving behind ugly marks that tarnish its appearance. Instead, opt for soft cloths or non-abrasive sponges that treat your stainless steel gently, preserving its smooth, shiny surface.
Avoid cleaning products containing chloride or other harmful chemicals
Next on the no-no list are cleaning products containing chloride or other harmful chemicals. These substances can cause pitting and corrosion that damage stainless steel over time. Always check the label of any cleaning product before using it on stainless steel. If you spot harsh substances, leave the stuff on the shelf.
Look for galvanic corrosion, especially in moist environments
Galvanic corrosion is another issue to watch out for, especially if your stainless steel is in a moist environment. This type of corrosion occurs when two different metals are in contact with an electrolyte, like water. To prevent this, ensure your stainless steel is dry and not in contact with other metals.
Use warm water and mild detergent or soap for basic cleaning
Now, onto the cleaning! Warm water and mild detergent or soap will do the trick for basic cleaning. Simply wash the surface with a soft cloth, rinse thoroughly, and dry immediately to prevent water spots. This simple routine can keep your stainless steel looking pristine day in and day out.
Always wear safety gear when cleaning stainless steel
Safety first! Always remember to wear safety gear when cleaning stainless steel. Gloves can protect your hands from sharp edges, and goggles can shield your eyes from any cleaning product splashes.
Follow the recommended procedures for cleaning products
Finally, always follow the recommended procedures for any cleaning products you use. Read the instructions carefully, and adhere to them strictly. Doing so ensures you’re using the product as intended and getting the most out of its cleaning power.
Process of 316 Stainless Plate
Preparing the material
The process for manufacturing stainless 316 plates begins with collecting the right types of alloys used as the primary material. Generally, this includes iron as the base metal, with significant portions of chromium, nickel, and molybdenum. These raw materials underg.
Smelting the alloys
The alloy mix is then taken through a smelting process. Here, the raw materials are heated to incredibly high temperatures in a furnace or an electric arc furnace, which reaches up to 3000 degrees fahrenheit. This high temperature transforms solid metal into molten form, ensuring the mixture of elements is thoroughly combined.
Casting process
Once the homogenized metal has been achieved, it is poured into molds to form ‘ingots,’ or basic shapes of the metal. This is typically done in a controlled environment to avoid impurities or changes in the metal’s composition. The ingots are allowed to cool and solidify, ready for the next step in creating the stainless 316 plates.
Forming the plates
The solid ingots are now ready for further processing to become stainless 316 plates. This section describes the vital steps involved in shaping and transforming the ingots into the flat, uniform plates that are so commonly recognized.
Hot rolling
The ingots are heated to high temperatures that reach just below the metal’s recrystallization temperature. At this stage, the metal is malleable enough to withstand shaping without compromising its structure. The heated ingots pass through a series of rollers, which gradually decrease the thickness and increase the length and width, transforming them into ‘slabs.’
Cold rolling
The slabs, now somewhat close to the desired thickness and shape, are then cold-rolled between polished rolls to give a smoother, more finished surface. This process also helps improve the metal’s strength and impart directional grain, which is critical for the next steps in the manufacturing process.
Annealing
To relieve the stress caused by the rolling process and to soften the steel for further work, the metal is then annealed. This is where the stainless 316 plates are heated to a specific temperature and then allowed to cool slowly. Annealing reduces hardness and increases ductility, which helps prevent cracking during subsequent manufacturing steps.
