About the Steel
SS304L stainless steel is a low-carbon version of the widely used SS304 grade, designed to offer excellent corrosion resistance while minimizing the risk of intergranular corrosion during welding or high-temperature exposure. Its low carbon content (≤ 0.03%) makes it ideal for welded structures where post-weld heat treatment is not feasible. SS304L maintains good strength, high ductility, and excellent toughness across a broad temperature range, including cryogenic conditions. It is non-magnetic in the annealed state but may become slightly magnetic after cold working. This steel is widely used in chemical, food processing, pharmaceutical, and architectural applications due to its versatility and durability.
