AISI 410Cb XM 30 UNS S41040 Niobium-Modified Martensitic Turbine Blade Steel Forgings Blades, Vanes & Bars

Product Description

Jiangsu Liangyi is an ISO 9001:2015-certified forging manufacturer in China supplying AISI 410Cb / UNS S41040 open-die forgings and bars to steam-turbine, gas-turbine and compressor-blade projects in India and worldwide, to ASTM A582 / A479 and AMS 5773.

Why AISI 410Cb / XM-30 / UNS S41040 for Indian turbine-blade projects

410Cb is a niobium-modified 12% Cr martensitic steel purpose-built for turbine blade forgings finer grain, better toughness and fatigue resistance than standard 410, backed by an established ASTM XM-30 / AMS 5773 specification base. For India's power-generation and industrial-turbine sectors, 410Cb suits steam- and gas-turbine blades, vanes and compressor blades.

Documented capability

Steam turbines: blades and vanes for LP/HP/IP stages.

Gas turbines/industrial turbines: blades and vanes.

Compressor/rotating equipment: compressor blades, blade blanks, preforms.

General: discs, hubs, sleeves, custom forgings.

Product range for Indian buyers
