EN19 is a highly versatile, high-strength alloy steel known for its exceptional elasticity and mechanical properties. It is primarily supplied in a readily machineable condition, commonly referred to as “T” condition, which makes it suitable for a wide range of engineering and industrial applications.
This steel is highly regarded for its excellent combination of toughness, ductility, and shock resistance, allowing it to withstand heavy loads and harsh operating conditions without compromising performance. Additionally, EN19 exhibits outstanding resistance to wear and abrasion, making it an ideal material for manufacturing components subjected to repeated stress and friction.
