826M40 - 2.5% Nickel-Chromium-Molybdenum Through Hardening Steel

Surcharge

Scrap has fallen again for June 2019 on the back of reduced demand. Combined with slight falls in alloys, this has seen an overall reduction in surcharges this month.

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

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.
