309/309S Stainless steel coil

The material 309 is a quality standard for furnaces and other high temperature components. Compared to other grades for applications and due to the high tensile strength at elevated temperatures, 309 is ideal for application where special emphasis is placed on mechanical properties.

309S is a variant of 309 stainless steel with low carbon content, which is used for occasions requiring welding. The lower carbon content minimizes the precipitation of carbides in the heat affected zone near the weld, which may lead to intergranular corrosion (welding corrosion) of stainless steel in some environments.
