904L Stainless Plate
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, which makes it have higher high temperature oxidation resistance, pitting resistance, and resistance to reducing acid (eg, sulfuric acid).

Product Introduction
Stainless Steel Plates & Coils-904L
AISI 904L stainless steel (UNS N08904) belongs to the group of high alloy austenitic stainless steels. In comparison to 316L, SS904L contains less carbon (C) and higher amounts of chromium (Cr), as well as approximately two times more nickel (Ni) and molybdenum (Mo). This attribute gives it a greater capacity to endure elevated temperatures while experiencing oxidation, resist the formation of pits, and withstand exposure to reducing acids like sulfuric acid. The presence of nitrogen can decrease the speed at which chromium carbide precipitation occurs, resulting in a lower susceptibility to sensitization. This also enhances the material’s ability to withstand damage from crevice and pitting corrosion induced by chloride. The incorporation of copper (Cu) is particularly advantageous as it makes the material resistant to all levels of sulfuric acid concentration.
Applications
904L stainless steel (SS904L) is used in petroleum, chemical, fertilizer, marine development towers, tanks, pipes and tubes and heat exchangers. Rolex and other watch manufacturers also use it to make watches.
Heat Treatment
Annealing: The recommended annealing temperature for 904L wrought steel is 1095 °C (2000 °F).
Corrosion
Type 304 stainless steel is suitable for mild foods and vegetables, but acidic substances such as sauces and pickle liquors can be more corrosive and cause pitting corrosion on type 316 stainless steel. For enhanced resistance to pitting, high-alloy 904L stainless steel (SS904L) is a recommended option.
