What is EN 91 Sheet and Plates?
The composition of EN 24 Sheets and Plates includes carbon, manganese, chromium, molybdenum, and nickel, creating a well-balanced chemical structure that delivers high tensile strength, hardness, and toughness. They showcase impressive yield and ultimate tensile strength, good elongation, and outstanding impact resistance. The alloying elements enhance hardenability, making EN 24 perfect for heat treatment processes like quenching and tempering, which boost wear resistance and fatigue strength. These mechanical characteristics make it an excellent choice for critical applications in high-stress environments.
