    Stainless Steel 304L


    304L is a variant of 304 stainless steel with a lower carbon content for applications requiring soldering. The lower carbon content minimizes the precipitation of carbides in the heat affected zone near the weld, which may result in intergranular corrosion (weld erosion) in certain environments.


    Widely used in the production of equipment and parts that require good overall performance (corrosion resistance and formability).
