Stainless Steel 321 Rods

Stainless Steel 321 Bars and Rods are crafted from an austenitic stainless steel alloy that contains chromium (17–19%) and nickel (9–13%), with titanium added to prevent carbide precipitation. This stabilization significantly improves resistance to intergranular corrosion, especially after welding, while also providing excellent strength at high temperatures. In terms of mechanics, 321 bars and rods deliver good tensile and yield strength, toughness, and ductility. Their thermal stability and corrosion resistance make them perfect for critical applications in challenging environments.
