ASTM A240 317L stainless steel, also known as ultra-low carbon stainless steel, is a versatile stainless steel material, which is widely used to produce equipment and components requiring good comprehensive properties (corrosion resistance and formability). ASTM A240 317L stainless steel is a variant of
ASTM A240 317L stainless steel with low carbon content and is used for welding occasions. Lower carbon content minimizes the amount of carbides precipitated in the heat affected zone near the weld, and the precipitation of carbides may lead to intergranular corrosion (welding corrosion) of stainless steel in some environments.
