EN 353 is a high-quality, case-hardened steel that is widely used in manufacturing components that require high strength, toughness, and wear resistance. With a carbon content of around 0.18–0.20%, it is alloyed with elements such as chromium, nickel, and molybdenum, which enhance its hardenability and fatigue resistance. EN 353 is particularly well-suited for producing components that are subjected to heavy loads and high stress, including shafts, gears, and camshafts, often found in automotive, machinery, and engineering applications. The steel's case-hardening properties allow for a hard outer surface, providing excellent wear resistance, while maintaining a tough, ductile core for shock resistance. EN 353 can be heat treated to achieve the desired hardness and strength, making it versatile for various demanding applications. It is available in forms like bars and forgings and is typically supplied in a normalized or hardened condition, depending on the specific application requirements. Its combination of high wear resistance and core toughness makes EN 353 a preferred choice for critical engineering components.
