What is Stainless Steel 321/321H Round bar ?

SS 321 is also recognized as UNS S32100 stabilized round bar which is generally adopted across high corrosive environments more specifically intergranular corrosions. Even under the chromium carbide atmospheres limiting the range of 800-1500 Degree F, this grade performs very well. Stainless Steel 321 is stabilized grade and hence, offers relief from the carbide formation, all thanks to its titanium addition into the material. SS 321 round bars have outstanding mechanical and chemical properties that result in benefits across high service temperature environments. In terms of physical properties, SS 321 round bars also give excellent results against stress and creep rupture atmospheres even one step ahead than other steel grades such as SS 304 , and 304L that are also known to resist sensitization and intergranular atmospheres.

SS 321H round bars is a higher carbon version steel bar that has a proportion of carbon in the range from 0.04-0.10%. It came into existence to improve resistance across creep resistance at the temperature up to 1000 Degree F. SS 321 and 321H bars both do not support heat treatment, and hence can be hardened only and only through cold working. However, SS 321 and 321H can be welded and fabricated through standard practices. The applications that employ SS 321 and 321H round bars are food processing, chemical processing, waste treatment, petroleum refining, and many more.
