En Series Steel

Product Details:

EN 10083-3 30MnB5 is a boron-alloyed steel grade developed for applications requiring high strength, excellent hardenability, and good toughness after heat treatment. With a nominal carbon content of around 0.30% and the controlled addition of boron and manganese, 30MnB5 steel provides significantly improved hardenability compared to conventional carbon steels, allowing uniform mechanical properties even in thicker sections. Supplied in bar form, EN 10083-3 30MnB5 alloy steel is widely used in automotive, forging, and heavy engineering 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 30MnB5 alloy steel bars.
