321 Cold Rolled Stainless Steel Coil

OES Metal’s 321 Stainless Steel Coils are austenitic stainless steel products designed to withstand high temperatures and resist intergranular corrosion. Stabilized with titanium, 321 stainless steel offers superior performance in demanding applications, including aerospace, chemical processing, and heat exchangers.

When you’re dealing with really high temperatures, you need materials that can keep up. That’s where our 321 Stainless Steel Coils come in—they’re specially designed to handle extreme heat and resist corrosion. Thanks to the addition of titanium, these coils do a great job preventing intergranular corrosion and stay strong even when used continuously up to about 1500°F (816°C). Pretty impressive, right?

They’re a perfect fit for manufacturing environments that push materials to the limit. Whether it’s building aerospace parts, automotive exhaust systems, heat exchangers, or components for industrial furnaces, these coils are versatile. Plus, the titanium helps prevent carbide precipitation during welding or in high-temp conditions, so you get consistent, reliable performance every time.
