Detail
Product Description:
321 stainless steel round bars are titanium-stabilized austenitic stainless steel, widely known for their excellent high-temperature resistance and intergranular corrosion resistance. 321 stainless steel can maintain its strength and stability at temperatures up to 800°C, making it particularly suitable for high-temperature processing and welding applications in industries such as aerospace, chemical equipment, and high-temperature furnace tubes.
321 stainless steel round bars are renowned for their outstanding intergranular corrosion resistance and high-temperature strength, making them an ideal material for welding and heat treatment in high-temperature environments. The addition of titanium stabilizes the structure of 321 stainless steel, preventing carbide precipitation at high temperatures, which significantly enhances the material’s resistance to intergranular corrosion. This makes 321 stainless steel particularly well-suited for long-term use in the 550°C to 800°C temperature range, finding extensive applications in aerospace, exhaust systems, chemical processing equipment, and high-temperature furnace tubes. Additionally, 321 stainless steel offers good mechanical properties and workability, allowing it to withstand harsh industrial conditions and ensuring the safety and durability of equipment. Whether in high-temperature environments or applications requiring corrosion resistance, 321 stainless steel round bars are a preferred choice for their stability and durability.
