Corrosion Resistance

1,exhibits good general corrosion resistance that is comparable to 304.

2,developed for use in the chromium carbide precipitation range of 1800 - 1500°F (427 - 816°C) .

3,can be used in most diluted organic acids at moderate temperatures .

4,can be used in pure phosphoric acid at lower temperatures.

5,can be used in up to 10% diluted solutions at elevated temperatures.

6,resists polythionic acid stress corrosion cracking in hydrocarbon service.

7, utilized in chloride or fluoride free caustic solutions at moderate temperatures.

8, does not perform well in chloride solutions, even in small concentrations, or in sulfuric acid service.

321/H can be easily welded and processed by standard shop fabrication practices.

Hot Forming

1,Working temperatures of 2100 - 2300°F (1149 - 1260°C) are recommended for forging, upsetting and other hot working processes.

2,Alloy not suitable for work at temperatures below 1700°F (927°C).

3,Material must be water quenched or fully annealed after working to re-attain maximum corrosion resistance.

Cold Forming

1,Quite ductile and forms easily.
