304L Stainless Steel Pipe Description
304L stainless steel pipe is a variation of 304 stainless steel pipe with a lower carbon content, often employed in welding applications. The reduced carbon content significantly diminishes the precipitation of carbides in the heat-affected zone near the weld, which is associated with intergranular corrosion of stainless steel in specific environments. Notably, the annealing of weld joints prior to using the completed metal form is unnecessary with 304L, saving time and effort. In general, both 304 and 304L stainless steel plates can be utilized for many of the same applications, with differences often not significant enough to favor one over the other. 304L stainless steel plate is more commonly used in fields such as food processing equipment, building materials, and automobile parts.
