Product Description

Jiangsu Liangyi is an ISO 9001:2015-certified alloy-steel forging manufacturer in China supplying AISI 6150 / 51CrV4 / W.Nr. 1.8159 (Cr-V spring steel) open-die forgings, seamless rolled rings and shafts to mining, gear-transmission, power, cement and oil & gas projects in India and worldwide, to ASTM A29 / EN 10083-3.

Why AISI 6150 / 51CrV4 for Indian mining, gear-drive and power projects

AISI 6150 is a chromium-vanadium spring/alloy steel with high hardenability and wear, shock and fatigue resistance, an upgrade over 5150 and 4140 under cyclic load. For India's mining, gear-transmission, cement and power sectors, it suits eccentric and gear shafts, gear rings, slewing races, pinions, torsion bars and heavy springs.

Documented capability

Mining: eccentric/gear shafts, slewing races, gear rings, transmission parts for crushers/excavators.

Gear drives/power: gear/pinion shafts, gear wheels, coupling/turbine shafts, spindles.

Springs: heavy springs, torsion bars, shock-absorber parts.

Product range for Indian buyers

Round/square/flat/rectangular bars, step rods; seamless rolled rings, riding gear rings, slewing races, gear rings; gear/pinion/coupling/turbine shafts, spindles, gear wheels, crankshafts; torsion bars, springs; sleeves, housings, discs.
