Description
EN36C Round Bar / 832M13 Round Bars
EN36C Round Bar / 832M13 Grade Steel is a Nickel Chromium Alloy Case Hardening steel that is specified for heavy duty highly-stressed applications.
When carburised and hardened cores 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 EN36A / 655M13 and improves its core strength after heat treatment.
832M13 steel is still often referred to as EN36C steel – its equivalent grade under the previous BS 970: 1955 standard.
