Carbon Steel EN-31 R-100 Bars and Rods have a chemical composition of roughly 0.90–1.20% carbon, 1.00–1.60% chromium, and 0.30–0.75% manganese to provide high hardness and wear resistance. The mechanical characteristics consist of 750–850 MPa tensile strength, 450–600 MPa yield strength, and 12–16% elongation, along with good hardness and machinability. EN-31 R-100 is thus best suited for precise applications demanding toughness and durability. Its strength along with resistance to deformation and ability to resist high-stress applications makes it a good fit for making automobile parts, cutting tools, dies, and heavy machinery parts.
