1.8070 21CrMoV5 11 Low Alloy Cr Mo V Steel Forgings for Large Steam Turbine Rotors and High Temperature Bolting Bars, Discs and Rings Jiangsu Liangyi

Product Description

Jiangsu Liangyi is an ISO 9001:2015-certified forging manufacturer in China supplying 1.8070 / 21CrMoV5-11 open-die forgings, seamless rolled rings, discs and bars to steam-turbine, power-generation and high-temperature bolting projects in India and worldwide, to EN 10269 and DIN 17240.

Why 1.8070 / 21CrMoV5-11 for Indian large-rotor projects

21CrMoV5-11 is a low-alloy Cr-Mo-V creep-resisting steel with excellent forgeability and through-hardenability in the largest sections, plus reliable creep-rupture strength around 530550 C a proven choice where section size and toughness matter as much as peak creep strength. For India's power-generation and heavy-forging sectors, 1.8070 suits large rotor shafts, discs, high-temperature bolting and couplings.

Documented capability

Steam turbines/power: large-section rotor shafts and discs, couplings.

High-temperature bolting: studs, bolts, nuts to 530550 C.

Large-forging capability: massive sections requiring through-hardenability.

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

Product range for Indian buyers

Forged steam-turbine rotor shafts and discs; large-section rotor forgings; high-temperature bolts, studs and nuts; couplings and shafts; round/square/flat/rectangular bars; hollow bars, sleeves, hubs.
