Credibility ,Type 321 Stainless Steel (UNS S32100) is an austenitic stainless steel angle bars that has fives times more titanium than carbon in its content. The increased titanium level aids in preventing carbide precipitation during welding. As a result, Type 321 Stainless Steel is both creep resistant and resistant to oxidation.
321 stainless steel flat rolled coil is generally used in applications that require sustainability to high intermittent temperatures.
