Уникальные особенности:

The primary advantage of 321 stainless steel sheet over standard 304 stainless steel is its addition of titanium, which stabilizes the structure and prevents carbide precipitation during welding and high-temperature service. This feature makes 321 stainless steel ideal for applications where the material will be exposed to temperatures above 500°C (932°F). Additionally, 321 stainless steel offers excellent resistance to a variety of chemicals and oxidative environments, including those found in the chemical, petrochemical, and automotive industries. Its excellent weldability, high-temperature resistance, and overall durability make it a preferred material for harsh industrial conditions.
