Global leader in stainless steel sheet fabrication services
Daxun 321 Stainless Steel Plate (UNS S32100) is a titanium-stabilized austenitic stainless steel with excellent resistance to intergranular corrosion. This grade is designed for high temperature applications up to 1500°F (815°C), where the addition of titanium stabilizes the material against the formation of chromium carbides. Since titanium has a greater affinity for carbon than chromium, titanium carbides occur within the grains rather than at the grain boundaries. While its annealed corrosion resistance is comparable to 304 and 304L, it has stronger creep and stress rupture properties. These properties make it suitable for pressure vessel and boiler applications. 321 Stainless Steel is non-magnetic and heat resistant, allowing long-term use at high temperatures.
Daxun Alloys stocks 321 Alloy stainless steel plate in thicknesses ranging from 3/16″ to 4″. You can also order the high carbon version 321H Alloy (UNS S32109) in the same thickness range.The alloy can be used in most dilute organic acids at moderate temperatures, pure phosphoric acid at lower temperatures, and dilute solutions up to 10% at elevated temperatures. Alloy 321 resists polythionic acid stress corrosion cracking in hydrocarbon service. It can also be used in alkaline solutions without chlorides or fluorides at moderate temperatures. Alloy 321 does not perform well in chloride solutions (even at low concentrations) or in sulfuric acid environments.
