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.
