Alloy Steel EN9
Alloy Steel EN9
Apar Alloys offers Alloy Steel EN9, a medium carbon steel known for its high tensile strength, wear resistance, and excellent machinability. This versatile grade is widely used in automotive, engineering, and machinery components, where a combination of strength, toughness, and durability is required. EN9 performs exceptionally well under heat-treated or normalized conditions, providing a balanced blend of hardness and ductility for a wide range of industrial applications.
With its well-balanced composition and mechanical stability, EN9 delivers reliable performance under impact and frictional stress. It offers good machinability in the annealed condition and can be flame or induction hardened to achieve enhanced surface hardness and wear life. Apar Alloys is Supplier and Stockist of Alloy Steel EN9, providing high-quality materials that meet international standards. The grade’s toughness and resilience make it ideal for shafts, gears, and machine parts that require long-lasting service even under repeated load conditions.
