Type 304 Stainless Steel is a variation of the base 18-8 grade, with a higher chromium and lower carbon content. The lower carbon content minimizes chromium carbide precipitation due to welding and its susceptibility to intergranular corrosion. In some instances Type 304 can be used in the "as-welded" condition. Type 304L is an extra low-carbon variation of Type 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. In many cases it eliminates the necessity of annealing weldments except for applications specifying stress relief. Type 304L has slightly lower mechanical properties than Type 304. High strength, excellent corrosion resistance and excellent formability make Types 304 and 304L Stainless Steels useful for many applications. Typical uses include architectural moldings and trim, kitchen equipment, as well as chemical, textile, paper, pharmaceutical and chemical industry processing equipment.For severely corrosive environments or when welding is required, Type 304L is preferred because of its greater immunity to intergranular corrosion.
