What is 321H stainless steel?
Stainless steel 321H is a general-purpose austenitic stainless steel that is stabilized against carbide precipitation and designed to work within the carbide precipitation temperature range 427 to 816°C (800 to 1500°F). It is non-magnetic in the annealed condition and can be hardened only by cold working.
