EN26 826M40 1.6745 High-Tensile Forgings for Aerospace, Oil & Gas Heavy Drives Crank Gear Shafts, Connecting Rods, Rings Fasteners

Product Description

Jiangsu Liangyi is an ISO 9001:2015-certified alloy-steel forging manufacturer in China supplying EN26 / 826M40 (1.6745 / 40NiCrMo10-5) open-die forgings, seamless rolled rings and shafts to aerospace, oil & gas, automotive, power and heavy-machinery projects in India and worldwide, to BS 970.

Why EN26 / 826M40 for Indian aerospace, oil & gas and heavy-drive projects

EN26 is a 2.5% Ni-Cr-Mo through-hardening high-tensile steel with high hardenability, reaching tensile strengths from 850 to over 1,550 MPa with toughness retained in very large sections, and higher tensile than 4140, 4340 or EN25. For India's aerospace, defence, oil & gas and heavy-machinery sectors, 826M40 suits crankshafts, heavy-duty gears, connecting rods, turbine discs, high-strength fasteners and ordnance parts.

Documented capability

Aerospace/defence: undercarriage and airframe parts, aero-engine parts, turbine discs, ordnance parts.

Oil & gas: heavy shafts, gears, mandrel bars, high-strength fasteners.

Automotive/power: crankshafts, transmission/differential shafts, heavy-duty gears, connecting rods, motor shafts.

Product range for Indian buyers

Round/square/flat/rectangular bars; crankshafts, differential/transmission/gear/pinion shafts, spindles, axles, motor shafts; heavy-duty gears, connecting rods; seamless rolled rings, gear rings, bearing races; high-strength bolts/studs, turbine discs, gas bottles, mandrel bars; sleeves, hollow bars.
