EN36C (832M13) Engineering steel

832M13 grade steel is a nickel-chromium alloy case hardening steel that is specified for heavy duty highly – stressed applications which High Peak Steels supply for such as High duty gears for aircraft and Steering Worms.

When carburised and hardened the core strengths of 850 – 1230 n/mm2 are attainable. The presence of chromium increases hardenability, while the nickel content increases toughness and resistance to stock.

The addition of molybdenum further increases this material’s hardenability when compared with grade 655M13 and improves its core strength after heat treatment.

The nickel acts to increase the toughness and resistance to shock.

832M13 is still often referred to as EN36C steel – its equivalent grade under the previous BS 970: 1955 standard.
