321 stainless steel
321 stainless steel is a heat-resistant and titanium-stable Austenite alloy, which is generally used in the temperature range of 1000o - 1600oF.321 stainless steel is mainly used for continuous and intermittent operation of carbide precipitation temperature in the range of 800o - 1500oF. 321 stainless steel is similar to 304 stainless steel, but the titanium content is at least five times higher than the carbon content. The addition of titanium can reduce or prevent the precipitation of carbide during welding under working conditions of 800o - 1500of.In order to provide optimal resistance to intergranular corrosion and stress corrosion cracking of PTC at an operating temperature of 1500o - 1650oF, air cooling can be used.
What are the characteristics of 321 stainless steel?
• Oxidation resistance at 1600oF
• Stability against intergranular corrosion in the area affected by welding heat (Beam)
• Stress corrosion cracking resistance of Thiocyanate

Application
Stainless steel pipe is a kind of hollow round steel, widely used in oil, chemical industry, medical treatment, food, light industry, mechanical instruments and other industrial transport pipes and mechanical components. In addition, it has the same bending and torque resistance, light weight, so it is also widely used in the manufacture of mechanical parts and engineering structures.
