China 36NiCrMo16-Alloy steel

5/5

China 36NiCrMo16-Alloy steel is defined as a heat treatable and low alloy steel which has 0.8% Cr, 0.2% Mo and 1.8% Ni as strengthening alloy elements.

China 36NiCrMo16-Alloy steel is defined as a heat treatable and low alloy steel which has 0.8% Cr, 0.2% Mo and 1.8% Ni as strengthening alloy elements.Compared with AISI 4140,it has higher strength and toughness,also it has very good fatigue resistance, wear resistance and atmospheric corrosion resistance.36CrNiMo4 / 1.6511 is generally supplied in hardened and tempered condition with the tensile range of 930 – 1080 Mpa ,hardness 280-320HB.Pre hardened and tempered 4340 can be further surface hardened by flame or induction hardening and by nitriding.

  • EN 10083-3: 2006 Steels for quenching and tempering. Technical delivery conditions for alloy steels
  • EN 10250-3: 2000 Open steel die forgings for general engineering purposes. Alloy special steels

China 36NiCrMo16-Alloy steel is often used in preference to AISI 4140 at the higher strength levels because of its better hardenability and improved CVN impact toughness.

Typical applications include:Heavy-duty axles, shafts, heavy-duty gears,spindles, pins, studs, collets, bolts, couplings,sprockets, pinions, torsion bars, connecting rods,crow bars, conveyor parts,forged hydraulic,forged steel crankshafts etc.
