Sri Lanka 309 309S Hot Rolled Stainless Steel Coil

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.

201 stainless steel coil is mainly used as decorative pipe, industrial pipe and some shallow stretched products.201 stainless steel coil is mainly used for high temperature applications. High temperature applications require strong sensitization resistance to prevent intergranular corrosion at lower temperatures.
