Yousef Steel, a trusted steel manufacturer and supplier located in Riyadh, Saudi Arabia, proudly offers top-quality **EN9 sheets and plates** that are perfect for applications demanding high surface hardness and solid mechanical strength. EN9 is a medium carbon steel grade celebrated for its excellent wear resistance and decent tensile strength, making it an ideal choice for components that face friction and mechanical stress. Yousef Steel guarantees precise manufacturing, dimensional accuracy, and a reliable supply for a variety of industrial, engineering, and fabrication needs.
Typically, EN9 contains 0.50–0.60% carbon and 0.50–0.80% manganese, which contribute to its remarkable hardness and strength after heat treatment. In its untreated state, it provides moderate machinability and a good surface finish, while heat-treated EN9 plates can achieve a tensile strength range of 600–800 MPa. This grade can be flame or induction hardened to enhance wear resistance while maintaining core toughness. EN9 steel is also suitable for oil quenching and tempering, striking a great balance between hardness and machinability.
