321 Stainless Steel Sheet | High Temp SS Plate | China Manufacturer

Product Overview

321 stainless steel sheet is a titanium-stabilized austenitic stainless steel known for its excellent resistance to intergranular corrosion and superior high-temperature performance. It is specifically designed for applications involving continuous or intermittent exposure to elevated temperatures (up to 870°C).
Compared to 304, 321 offers better weldability and thermal stability, making it ideal for heat exchangers, exhaust systems, and pressure vessels.
