STEEL PROPERTIES

No hardening risks, no hardening costs and time saving (e.g, no waiting for heat treatment) including lower tool cost(e.g, no distortion to rectify),
modifications easily carried out, can subsequently nitrided to increase surface wear resistance or locally fame hardened to reduce surface damage
