Carbon Steel EN-31 R-100 Bars are a type of alloy steel characterized by high carbon and chromium content. The typical composition includes Carbon (0.90–1.20%), Chromium (1.0–1.60%), and Manganese (0.30–0.75%), along with trace amounts of Silicon, Sulphur, and Phosphorus. This steel grade is known for its exceptional hardness, wear resistance, and strength. It boasts a tensile strength of approximately 850–1000 MPa and demonstrates good toughness when properly heat-treated. The hardness can range from 60–65 HRC, depending on the heat treatment process. These mechanical properties make EN-31 R-100 Bars perfect for components that require high surface hardness and dimensional stability.
