EN26 is a 2.5% Nickel-Chrome-Moly high hardenability, high tensile steel & is generally supplied hardened and tempered (to condition V). Pre hardened and tempered EN26 can be further surface hardened by flame or induction hardening as well as nitriding.
EN26 is used for Undercarriages, aero-engine and air frame 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.
FOllowing is 826M40 forging parts melting requirement
EAF: Electric Arc Furnace
EAF+LF+VD: Refined-smelting and vacuum degassing
EAF+ESR: Electro Slag Remelting
EAF+PESR: protective atmosphere Electro Slag Remelting
VIM+PESR: Vacuum induction melting
Chemical composition of EN26 forging shafts is as following
Carbon 0.36 0.44
Silicon 0.10 0.35
Manganese 0.45 0.70
Nickel 2.30 2.80
Chromium 0.50 0.80
Molybdenum 0.45 0.65
Phosphorous 0 0.04
Sulphur 0 0.04
Following is heat treatment way of EN26 forged parts
Annealing treatment of en 26 forged bars:Heat to 790 oC - 840 oC, hold until temperature is uniform throughout the section and cool in furnace.
Flame or Induction Hardening
Hardening of en26 forging shafts
Heat to 820 oC - 850 oC, hold until temperature is uniform throughout the section, soak for 10 - 15 minutes per 25 mm section, and quench in oil, water, or polymer as required.*Temper immediately while still hand warm.
Nitriding of 826M40 forging gear shafts
EN26 hardened and tempered round bar can also be successfully nitrided, giving a surface hardness of up to Rc 60. Nitriding is carried out at 490 oC - 530 oC, followed by slow cooling (no quench) reducing the problem of distortion. Parts can therefore be machined to near final size, leaving a grinding allowance only. The tensile strength of the core is usually not affected since the nitriding temperature range is generally below the original tempering temperature employed.N.B. Nickel is inert to the action of nitrogen and in general resists its diffusion into steel, and this can result in a lower case hardness or longer nitriding cycle times for steels containing nickel such as EN26.
Stress Relieving of en26 forged bars
Heat to 640 oC - 660 oC, hold until temperature is uniform throughout the section, soak for 1 hour per 25 mm section, and cool in still air.Tempering
Re-heat to 450 oC - 660 oC as required, hold until temperature is uniform throughout the section, soak for 1 hour per 25 mm of section, and cool in still air.N.B.Tempering should be avoided if possible within the range 250 oC - 450 oC due to temper brittleness.
Following is mechanical property of 826M40 EN26 forging material

Proof Stress (0.2%) if required (Mpa, Min) Ruling Section (mm)150 710
FOllowing is heat treatment way of EN26 forging material
Heat to 1150 oC - 1200 oC maximum, hold until temperature is uniform throughout the section, and commence forging immediately.Do not forge below 850 oC.Following forging operation the work piece should be cooled as slowly as possible in sand or dry lime etc..
