AISI 321 Grade Cold Rolled No.4 2B Hairline Stainless Steel Sheet

321 Stainless Steel Sheet Description:

Alloy 321 (UNS S32100) is stabilized stainless steel sheet which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500°F (427 to 816°C). Alloy 321 stainless steel sheet is stabilized against chromium carbide formation by the addition of titanium.

Alloy 321 stainless steel sheet is also advantageous for high temperature service because of its good mechanical properties. Alloy 321 stainless steel sheet offers higher creep and stress rupture properties than Alloy 304 and, particularly, Alloy 304L, which might also be considered for exposures where sensitization and intergranular corrosion are concerns.

321 Stainless Steel Sheet Corrosion Resistance:

Alloy 321 stainless steel sheet exhibits good general corrosion resistance that is comparable to 304. It was developed for use in the chromium carbide precipitation range of 1800 – 1500°F (427 – 816°C) where un-stabilized alloys such as 304 are subject to intergranular attack.

The alloy can be used in most diluted organic acids at moderate temperatures and in pure phosphoric acid at lower temperatures and up to 10% diluted solutions at elevated temperatures. Alloy 321 resists polythionic acid stress corrosion cracking in hydrocarbon service. It can also be utilized in chloride or fluoride free caustic solutions at moderate temperatures.

Alloy 321 stainless steel sheet does not perform well in chloride solutions, even in small concentrations, or in sulfuric acid service.

321 Stainless Steel Sheet Applications:
1) Aerospace – piston engine manifolds
2) Chemical Processing
3) Expansion Joints
4) Food Processing – equipment and storage
5) Petroleum Refining – polythionic acid service
6) Waste Treatment – thermal oxidizers
7) Pharmaceutical Production
