304L Stainless Steel Coil
304L stainless steel is remarkably similar to 304 stainless steel in their chemical composition with one key difference. the maximum carbon of 304L stainless steel content is set at 0.08%, whereas grade 304L stainless steel has a maximum carbon content of 0.03%. This is why the “L” in 304L can be interpreted as extra-low carbon. It is widely used in the production of equipment and parts that demand better corrosion resistance and formability.

304L Stainless Steel Coil Description
304L stainless steel coil is a variant of 304 stainless steel coil with a lower carbon content and is used where welding is involved. The lower carbon content minimizes the precipitation of carbides in the heat-affected zone close to the weld, and the precipitation of carbides may lead to intergranular corrosion of stainless steel in certain settings. Basically, using 304L spares the need to anneal weld joints prior to using the completed metal form, saving time and effort. Generally speaking, both 304 and 304L stainless steel coils can be used for many of the same applications. The differences are often minor enough that one isn’t considered massively more useful over the other. 304L stainless steel coil is widely used in fields such as food processing equipment, building materials, automobile parts.
