A Guide To 321H WIRE IN 2023
Stainless Steel 321 is a basic austenitic 18/8 steel (Grade 304) blend of chromium and nickel stabilized by Titanium (321) addition. SS 321 is used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425–850°C. Stainless Steel 321 is the grade of choice for applications in the temperature range of up to about 900°C, combining high strength, resistance to scaling, embrittlement, and phase stability with resistance to subsequent aqueous corrosion. It is protected from temperatures ranging from 800 to 1500° F. The metal displays high strength and resistance to various forms of corrosion, including that from an aqueous environment.
