722M24 grade steel is a chromium-molybdenum nitriding steel often supplied in the hardened and tempered condition (typically with 1075 N/mm² tensile strength).

After nitriding it develops a hard wear resistant case in the range of 61-65HRc with good resistance to shock and fatigue.

The relatively low temperature of the nitriding process produces components with a scale free surface and minimum distortion. No significant loss of surface hardness will result from operating temperature up to 500°C.

Size Range

32mm - 860mm Dia

Typical applications of 722M24 grade steel

  • Aircraft applications 

  • Crankshafts

  • Gears

  • Plastic moulds

  • Compressor discs

  • Pins

  • Spindles 

  • Bolts

722M24 steel is still often referred to as EN40B steel - its equivalent grade under the previous BS 970: 1955 standard.
