AISI 321 H material

AISI 321 H is comparable to AISI 321.
Good corrosion resistance is given in natural environmental media. (waters of rural and industrial atmosphere). The prerequisite is that chlorine and salt concentrations as well as concentrations of nitric or organic acids are low.

Automotive industry, construction industry, chemical industry, food industry, aviation and mechanical engineering.

In apparatus engineering often for parts with high mechanical stress. For parts in furnace construction: annealing furnaces, muffle furnaces, hardening boxes.
