321 Stainless Steel
-61 Products
|
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 carry 321 in hex bar, cold finish hex bar, rectangle bar, annealed rectangle bar, round bar, round tube, seamless round tube, and sheet/plate.
