1.4911 X8CrCoNiMo10 6 Advanced Cr Co Martensitic Steel Forgings for Gas and Steam Turbine Blades and Rotor Shafts Blades, Bars and Rings JIangsu Liangyi

Product Description

Jiangsu Liangyi is an ISO 9001:2015-certified forging manufacturer in China supplying 1.4911 / X8CrCoNiMo10-6 open-die forgings, seamless rolled rings and bars to gas-turbine, steam-turbine and combined-cycle power-plant projects in India and worldwide, to EN 10302.

Why 1.4911 / X8CrCoNiMo10-6 for Indian gas/steam turbine projects

1.4911 is an advanced cobalt-alloyed 10% Cr martensitic creep-resisting steel with higher tempering resistance than conventional Cr martensitic grades, strong creep-rupture strength, and thermal conductivity that reduces thermal-fatigue stress during start-up/shutdown cycling an important advantage for combined-cycle and peaking plants. For India's power-generation sector, 1.4911 suits turbine blades, compressor blades, IGVs, nozzle segments and rotor shafts.

Documented capability

Gas/steam turbines: turbine blades, compressor blades, IGVs, nozzle segments, diaphragm nozzles.

Rotating equipment: rotor shafts, journal/thrust bearings.

Combined-cycle/peaking plants: components subject to frequent thermal cycling.

General: bars, rods, blocks, plates, rings, custom forgings.

Product range for Indian buyers

Forged gas/steam turbine blades; compressor blades; IGVs; nozzle segments and diaphragm nozzles; rotor shafts; journal/thrust bearings; round/square/flat/rectangular bars and rods; forged blocks/plates; sleeves, rings.
