Austenitic Grade Welding Forming 321 Brushed Stainless Steel Strip Titanium Coated JIS DIN Prime
Grades 321 is the basic austenitic 18/8 steel (Grade 304) stabilised by Titanium (321) additions. This grade is used because it’s not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850°C. Grade 321 is the grade of choice for applications in the temperature range of up to about 900°C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion.
Like other austenitic grades, 321 has excellent forming and welding characteristics, are readily brake or roll formed and have outstanding welding characteristics. Post-weld annealing is not required. They also have excellent toughness, even down to cryogenic temperatures. Grade 321 does not polish well, so is not recommended for decorative applications.
Typical applications include:
Aircraft exhaust manifolds
Heating element tubing
Woven or welded screens for high temperature mineral processing
Spiral Welded tube for burner pipes and flues
