What’s the Difference Between Grade 304 and 304L Stainless ...

Jan 06, 2017 · This is the case with grade 304 and 304L stainless steel. These two alloys are remarkably similar—but there is one key difference. In grade 304 stainless, the maximum carbon content is set at 0.08%, whereas grade 304L stainless steel has a maximum carbon content of 0.03%. The “L” in 304L can be interpreted as meaning extra-low carbon.

SS304 vs SS316, 304 vs 316 Stainless Steel, Difference ...

Difference Between 304 and 316 Stainless Steel. The main difference between 304 vs 316 stainless steel is the content of Chromium (Cr), Nickel (Ni) and Molybdenum (Mo). 304 stainless steel doesn’t contain Molybdenum while SS316 contains 2%-3% molybdenum. In addition, AISI 304 has a 18% Chromium and 8% Nickel content while AISI 316 has a 16% Chromium and 10% Nickel.
