Stainless Steel Round Tube 321

Stainless Steel 321 Product Guide Product

Reinforced with titanium, 321 stainless steel excels in high temperature environments, providing resistance to cracking and corrosion. Additionally, 321 stainless resists scaling at higher temperatures. The addition of titanium means that welding is not suggested for this alloy. Typically used in aircraft engines, expansion joints, thermal equipment, refinery equipment, and high temperature chemical processing equipment.

 We offer 321 stainless steel tubing in seamless.
