Strain strength and resistance to wear:

This steel grade is generally destined to applications in which a high strain strength and a high resistance to wear under high alternate loads are required. Therefore its main components must have a high hardness, a high elastic limit and a high fatigue strength.

Hardenability:
Good hardenability; hardening must allow quenching in oil in order to reduce to the minimum the risk of hardening cracks or distortions and to minimize the subsequent grinding operations.
