Stainless Steel 304L developed to work in "as-welded" conditions, even in severe corrosive conditions.

304L Stainless Steel is an extra low-carbon variation of Stainless Steel 304 with a 0.03% maximum carbon content that eliminates carbide precipitation due to welding. As a result, this alloy can be used in the "as-welded" condition, even in severe corrosive conditions. It often eliminates the necessity of annealing weldments except for applications specifying stress relief. It has slightly lower mechanical properties than SS 304. It is common for UNS S30403 to be dual certified as 304 and 304L when the material meets both the lower carbon limit of Type 304L and the slightly higher strengths of Type 304.
