Product Description

Jiangsu Liangyi is an ISO 9001:2015-certified forging manufacturer in China supplying 1.4922 / X20CrMoV11-1 open-die forgings, seamless rolled rings, discs and bars to steam-turbine, power-generation and high-pressure-valve projects in India and worldwide, to EN 10269 and DIN 17240.

Why 1.4922 / X20CrMoV11-1 for Indian steam-turbine projects

"X20" is a martensitic Cr-Mo-V creep-resisting steel with a long, well-characterized creep-rupture database and continuous service capability to 565 C, making it the benchmark grade for HP/IP steam-turbine rotors, discs, blades, bolts and valve components. For India's power-generation and high-pressure-equipment sectors, 1.4922 suits rotor shafts, discs, blades, bolts and valve stems/bodies.

Documented capability

Steam turbines/power: rotor shafts, discs, blades/vanes, turbine bolts/studs, couplings.

Valves/high-pressure equipment: valve stems, spindles, bodies.

High-temperature bolting: studs, bolts, fasteners to 565 C.

General: hollow bars, sleeves, hubs, shafts, custom forgings.

Product range for Indian buyers

Forged rotor shafts and discs; turbine blades and vanes; turbine bolts and studs; valve stems, spindles and bodies; couplings and shafts; round/square/flat/rectangular bars; hollow bars, sleeves, hubs.
