Description

826M40 grade steel is a 2.5% nickel-chromium-molybdenum through hardening steel which has a high hardenability.

It may be treated in relatively large section sizes to produce tensile strengths ranging from 850 to over 1550 N/mm² combined with good ductility and resistance to stock.

Due to its high molybdenum content, the steel may normally be tempered in the range 300-550C without serious loss of impact values.

Good mechanical properties at low temperature can also be obtained.

Size Range

45mm - 405mm Dia

Typical applications of 826M40 grade steel

  • Undercarriages
  • Aero-engine and airframe parts
  • Heavy duty gears
  • Pinion connecting rods
  • Crank and differential shafts and other transmission parts
  • High strength bolts and studs
  • Electrical motor shafts
  • Turbine discs
  • Gas bottles
  • Mandrel bars for tube manufacture
  • Ordnance parts

826M40 steel is still often referred to as EN26 steel - its equivalent grade under the previous BS 970: 1955 standard.
