321 Stainless Steel Mesh

321 SS is a heat resistant steel containing titanium to form a carbide of low solid solubility for a reduced possibility of intergranular precipitation and of associated intergranular corrosion. 321 SS exhibits a high degree of resistance to corrosion and oxidation while possessing high creep strength. Type 321 is primarily used for welded construction and for parts intermittently heated within 900-1600°F. 321 SS is nonmagnetic when annealed, and slightly magnetic when cold worked. Typically used for aircraft exhaust manifolds, various jet engine parts, high temperature chemical handling equipment, and pressure vessels.
