Stainless Steel Sheet 321 is a high-strength, high-temperature-resistant stainless steel with good corrosion resistance and excellent oxidation resistance. 321 stainless steel has excellent high temperature resistance due to the addition of titanium, and it still has good stability and toughness in high temperature environments.
321 stainless steel composed chromium, nickel, and titanium elements, contributing to its great corrosion resistance in various corrosive environments. The addition of titanium provides protection against chromium carbide precipitation during welding and high-temperature applications, making 321 sheet suitable for use in environments where sensitization and intergranular corrosion are concerns.The carbon content in 321 steel is typically kept low to enhance its resistance to sensitization during prolonged exposure to high temperatures.
321 stainless steel is widely used in aerospace, petrochemical industry, railway transportation, machinery manufacturing, heat treatment industry and other fields.SS321 has high corrosion resistance and can resist various chemical corrosive media, such as acids, alkalis and salts. At the same time, it has high hardness and strength and can withstand high pressure and heavy load.
