ASTM A276 A479 321 stainless steel bar stock steel round bar
Product Description
When the temperature reaches 800-1500 ° F (427-816 ° C) and
chromium carbide precipitates, it can still maintain good
resistance to intergranular corrosion. Due to the addition of
titanium to the composition, 321 alloy can still maintain stability
in the case of chromium carbide formation.
Due to its excellent mechanical properties, 321 alloy stainless
steel has advantages in working in high temperature environments.
Compared with 304 alloy, 321 alloy stainless steel has better
ductility and resistance to stress fracture.
