655M13 case hardening steel

655M13 steel is a nickel-chromium alloy case-hardening steel that is specified for heavy duty highly-stressed applications. And it is  is suitable for deep hardening to develop a tough core.When carburised and hardened core strengths of 850 – 1230 N/mm² are attainable.Chromium increases hardenability whilst the nickel content increases toughness and resistance.
