Product Introduction
Stainless Steel Plates & Coils
GENERAL PROPERTIES:
Alloy 321 (UNS S32100) is an austenitic stainless steel stabilized with titanium, offering satisfactory resistance to general corrosion. Even when exposed to temperatures within the range where chromium carbides are prone to form, from 800 – 1500°F (427 – 816°C), this material demonstrates superior resistance to intergranular corrosion. The alloy can withstand oxidation up to 1500°F (816°C) and possesses superior creep and stress rupture characteristics compared to alloys 304 and 304L. Additionally, it has favorable toughness at low temperatures.
Alloy 321H (UNS S 32109) is a variant of the alloy that contains a higher carbon content (0.04 – 0.10). It was developed for enhanced creep resistance and for higher strength at temperatures above 1000oF (537°C). In most instances, the incorporation of carbon in the plate allows for dual certification. Heat treatment cannot be used to increase the strength of Alloy 321, as it can only be strengthened through cold working methods. This material is readily weldable and can be processed efficiently by standard shop fabrication practices.
COMMON APPLICATIONS:
Aerospace – piston engine manifolds
Chemical Processing
Expansion Joints
Food Processing – equipment and storage
Petroleum Refining – polythionic acid service
Waste Treatment – thermal oxidizers
