Stainless-steel 321 is a standard kind of austentic steel that could be very much like SS 304, however with improvements of titanium and also five times the carbon content. Because of the content of carbon within this higher steel alloy it decreases the risk of carbide precipitation for the period of welding. This higher metal alloy furnishes outstanding resistance to rust and also metabolism. SS 321 can be utilized for high-temperature service due to its good mechanized components. This also have high-quality creep and also stress rupture properties compared to SS 304. The higher steel alloy provides the same resistance to overall rust because of higher nickel and also chromium content.
