Alloy Steel

Product Details:

EN 10083-3 30CrNiMo8 is a high-performance chromium-nickel-molybdenum alloy steel grade designed for applications requiring very high strength, excellent toughness, and outstanding hardenability after heat treatment. With a nominal carbon content of around 0.30% and the balanced addition of chromium, nickel, and molybdenum, 30CrNiMo8 steel offers exceptional fatigue strength and impact resistance, even in large cross-section components. Supplied in plate and bar form, EN 10083-3 30CrNiMo8 alloy steel is widely used in heavy engineering, automotive, defense, and power transmission applications. This grade is manufactured in accordance with EN 10083-3, which specifies technical delivery conditions for alloy steels for quenching and tempering.

Ladhani Metal Corporation is a reliable manufacturer, supplier, and exporter of EN 10083-3 30CrNiMo8 alloy steel plates and bars.
