Heat Treatment Guide & Properties
EN-30B is primarily supplied in the annealed condition and then carburized, quenched, and tempered after machining. Proper heat treatment ensures a hard case with excellent core toughness and long service life.
Carburizing
Introduces carbon to the surface to increase wear resistance.
Quenching
Oil quench to achieve required surface hardness.
Tempering
Relieves stresses while maintaining case hardness.

■ Chemical Composition
EN-30B contains nickel and chromium as its primary alloying elements. Nickel improves core toughness and impact resistance, while chromium enhances hardenability and wear resistance. This composition ensures reliable performance for case-hardened components operating under heavy loads.
■ Mechanical Properties
After carburizing and heat treatment, EN-30B develops a high surface hardness combined with a tough core. This balance makes it suitable for components subjected to shock loads, wear, and repeated stress in transmission and mechanical systems.
