Product Description

Jiangsu Liangyi is an ISO 9001:2015-certified forging manufacturer in China supplying 1.4905 / X11CrMoWVNb9-1-1 open-die forgings, seamless rolled rings, valve bodies and pipe fittings to power-generation projects in India and worldwide, to EN 10222-2.

Why 1.4905 / "E911" for Indian power-plant projects

1.4905 is a modified 9Cr-Mo-W-V-Nb creep-resisting steel (the "E911" grade), a European collaborative-research alternative to P92, offering broadly comparable creep-rupture strength for power-plant service to 600620 C. For India's power-generation sector, 1.4905 suits main-steam and hot-reheat valve bodies, headers, manifolds and piping components where this specification is called for.

Documented capability

Power generation: main-steam and hot-reheat valve bodies, headers, manifolds.

Boiler/steam piping: pipe fittings, flanges, nozzles, forged tees.

European-specification projects: components per regional/historical project requirements.

General: bars, discs, hubs, sleeves, custom forgings.
