Carbon Steel EN-42 is a high-carbon spring steel grade, typically featuring 0.70–0.90% carbon, along with small amounts of manganese and silicon. This composition gives it remarkable hardness and tensile strength, usually ranging from 700 to 950 MPa, depending on the heat treatment process. EN-42 can be hardened and tempered to enhance its wear resistance and elasticity. It also boasts good machinability in its annealed state and responds effectively to quenching and tempering. Its toughness and fatigue strength make it an excellent choice for demanding mechanical applications, especially in components that face continuous flexing or stress.
