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
- Timing wheels
- Breech mechanisms
- Small arms parts
655M13 steel is still often referred to as EN36 steel - its equivalent grade under the previous BS 970: 1955 standard.
