High-Temperature 309/310 Stainless Steel

309/310 stainless steel has high levels of chromium and nickel to provide good corrosion resistance at elevated temperatures. Often used in heat exchangers and furnaces, this material maintains its corrosion resistance up to the maximum temperature.

Foil is often used as a heat-treating wrap in temperatures up to 2000° F. It is furnished with a crimping tool.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
