Stainless Steel 420 Bolts are martensitic fasteners made from stainless steel, featuring a significant amount of chromium—typically around 12–14%—and carbon content ranging from 0.15–0.40%. This unique blend results in impressive hardness and decent corrosion resistance. These bolts are known for their high tensile strength, good wear resistance, and the ability to achieve even greater hardness through heat treatment. Their mechanical properties usually include high tensile strength, enhanced fatigue resistance, and excellent edge retention. Thanks to their martensitic structure, SS 420 bolts are perfect for applications that demand both strength and moderate corrosion resistance in slightly aggressive environments.
