Stainless Steel 409 Sheet is especially useful for applications that require oxidation or corrosion protection beyond the capability of carbon sheet and coated steel. It offers economical corrosion resistance and good formability. Stainless Steel 409 Coil is readily welded by arc welding processes. When gauge thickness and weld joint geometry allow the use of gas-shielded metal-arc welding, joints having good properties are easily obtained. Stainless Steel 409 Strip offers scaling resistance at temperatures up to 675°C during continuous operation, and up to 815°C under intermittent conditions. These temperatures obtain from specific service environments. It must be preheated to a temperature of 150 to 260’C before welding.
