304L Stainless Steel | Stainless Steel Supply

304L stainless steel is a popular grade of austenitic stainless steel that is widely used in various industries due to its excellent corrosion resistance, good formability, and durability. It is a low-carbon variant of the 304 stainless steel

The “L” in 304L stands for “low carbon,” indicating that the steel contains less carbon than standard 304 steel. This reduces the risk of carbide precipitation in the heat-affected zones during welding, which can lead to intergranular corrosion and other forms of damage.
