| 321/321H Stainless Steel Sheet/Plate: |
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). The alloy resists oxidation to 1500°F (816°C) and has higher creep and stress rupture properties than alloys 304 and 304L. It also possesses good low temperature toughness.

| 321H Stainless Steel Sheet/Plate: |
Alloy 321 cannot be hardened by heat treatment, only by cold working. It can be easily welded and processed by standard shop fabrication practices.Alloy 321H (UNS S 32109) is the higher carbon (0.04 – 0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000oF (537°C). In most instances, the carbon content of the plate enables dual certification.

Corrosion Resistance
- exhibits good general corrosion resistance that is comparable to 304.
- developed for use in the chromium carbide precipitation range of 1800 – 1500°F (427 – 816°C) .
- can be used in most diluted organic acids at moderate temperatures .
- can be used in pure phosphoric acid at lower temperatures.
- can be used in up to 10% diluted solutions at elevated temperatures.
- resists polythionic acid stress corrosion cracking in hydrocarbon service.
- utilized in chloride or fluoride free caustic solutions at moderate temperatures.
- does not perform well in chloride solutions, even in small concentrations, or in sulfuric acid service.
