Description

655M13 grade steel is a nickel-chromium alloy case-hardening steel that is specified for heavy duty highly-stressed applications.

When carburised and hardened core strengths of 850 - 1230 N/mm² are attainable.

The presence of chromium increases hardenability whilst the nickel content increases toughness and resistance to stock.

Size Range

32mm - 860mm Dia

Typical applications of 655M13 grade steel

  • High duty gears for aircraft
  • Heavy vehicle and automobile transmission components
  • Steering worms
  • Track rod pins
