**Stainless Steel 321** is an austenitic stainless steel that’s stabilized with titanium, which helps prevent carbide precipitation during welding and when exposed to high temperatures (up to about 870°C). It offers corrosion resistance similar to 304 stainless steel but boasts improved high-temperature strength and stability. With a minimum tensile strength of 515 MPa and solid resistance to oxidation and creep, 321 stainless steel is particularly well-suited for high-heat and pressure situations where standard stainless steels might falter.
