Deciding whether to use grade 303 vs 304 stainless steel often comes down to determining what the application will be. C Si 304 S S Mn P S Cr Ni ; . Overview. 304L is a variation that has a lower carbon content. 5052 is not heat-treatable, but is stronger than most of the 5xxx series of aluminums. As the name implies, it is mostly alloyed with carbon. Stainless Steel; Gate Operators & Accessories; Accessories. Because of the addition of the sulfur, 303 alloy has improved machinability compared to 304 alloy. The cost of stainless steel typically depends on the alloys involved, and a large proportion of those costs comes down to the chromium content. Custom cut and 1ft, 2ft, 3ft, 4ft, 5ft, 6ft, 7ft, 8ft, and 10ft lengths. Often hardened and tempered via heat treatment. Carbon Steel makes up our other main category.
