321 Stainless Steel Plate
321 Stainless Steel Plate is a titanium-stabilized austenitic stainless steel, essentially a 304 grade with enhanced properties. The addition of titanium prevents chromium carbide precipitation, delivering superior resistance to intergranular corrosion after welding. This plate is crucial for applications that involve exposure to high heat and subsequent corrosive conditions, including aircraft exhaust manifolds, heat exchangers, furnace parts, thermal oxidizers, and chemical processing equipment where post-weld annealing is not feasible.
