About Stainless Steel Round Bar 321

Stainless Steel Round Bar 321 is derived from 304 stainless steel in its basic composition. They are distinguished by the addition of a very small amount of Titanium. The main distinction is the amount of carbon in each. Besides, the yield strength increases in direct proportion to the carbon content. In high temperature environments, our product offers advantages due to the good mechanical qualities of the material. Comparing our 321 rods to 304 alloy, it exhibits greater resistance and ductility to stress fracture. Furthermore, it can be utilized for anti-sensitization as well as intergranular corrosion applications.
