Carbon Steel EN-31 is a high-carbon steel that contains chromium, featuring about 1.0–1.2% carbon and 1.4% chromium. This unique blend gives it remarkable hardness, wear resistance, and tensile strength. Typically, EN-31 bars show a tensile strength of 850–1000 MPa and hardness levels between 60–65 HRC after heat treatment. The steel also offers good dimensional stability and resists deformation under high stress. Its mix of toughness, strength, and wear resistance makes it perfect for heavy-duty applications where long-lasting performance is essential.
