321 stainless steel plate
321 stainless steel plate is a high performance austenitic stainless steel that offers exceptional resistance to intergranular corrosion and excellent high temperature performance. This versatile material is stabilized with titanium, which prevents chromium carbide precipitation at elevated temperatures, making it particularly suitable for applications between 800°F and 1500°F (427°C to 816°C). The plate combines outstanding mechanical properties with superior corrosion resistance, making it an ideal choice for critical applications in various industries. Its chemical composition typically includes 17-19% chromium, 9-12% nickel, and small amounts of titanium, which work together to create a material that maintains its structural integrity even under extreme conditions. The 321 grade is widely recognized for its excellent weldability and post weld performance, eliminating the need for post weld heat treatment in most applications. This characteristic makes it particularly valuable in fabrication processes where stress relieving is not practical. The plate's unique properties make it essential in aerospace, chemical processing, heat exchangers, and pressure vessel applications where reliability and longevity are paramount.
