Carbon Steel EN-353 is a case-hardening alloy steel that generally contains 0.17–0.23% carbon, 0.90–1.20% nickel, 0.80–1.10% chromium, along with trace amounts of molybdenum and manganese. It boasts a robust, ductile core paired with a hard surface achieved through carburizing and heat treatment. EN-353 bars can reach surface hardness levels of up to 60 HRC and a core tensile strength ranging from 850 to 1000 MPa, making them perfect for wear-resistant applications. This alloy also delivers excellent toughness, fatigue strength, and impact resistance, ensuring reliable performance even under dynamic loads and challenging conditions.
