EN31 STEEL
EN31 for hardness, strength and wear resistance.
EN31 is a high-carbon alloy steel known for its exceptional hardness, strength, and wear resistance. It is typically supplied in a hardened and tempered condition, offering an excellent balance of toughness and durability. With alloying elements such as nickel, chromium, and molybdenum, EN31 exhibits superior tensile strength, ductility, and impact resistance.
- High tensile strength with excellent toughness
- Superior wear resistance and fatigue strength
- Good ductility and machinability (in annealed condition)
- Reliable performance at both low and elevated temperatures
- High external hardness combined with good internal strength
