Alloy 321 (UNS S32100) is stabilized stainless steel 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 steelis stabilized against chromium carbide formation by the addition of titanium.
Alloy 321 stainless steel is also advantageous for high temperature service because of its good mechanical properties. Alloy 321 stainless steel 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.
We can produce 321 stainless steel round rods, 321 forging, sheet, coil, and profiledstrip, Deformed steel,flat steel, mould,steel wire,have all specifications. With Bozhong Group production experience, strict control 321 chemical composition and 321 mechanical properties.From casting, forging, steel to hot and cold rolling process, heat treatment, etc, we have the control of professional engineers. We have advanced precision machining equipment, according to the requirements of users machining. in order to achieve the most satisfied with the user requirements.
