AISI 9310 14NiCrMo13 4 1.6657 Aircraft-Quality Gear Steel Forgings for Aerospace and Helicopter Transmissions Gears, Bearings and Bars Jiangsu Liangyi

Product Description

Jiangsu Liangyi is an ISO 9001:2015-certified forging manufacturer in China supplying AISI 9310 / 14NiCrMo13-4 (1.6657) open-die forgings, gear blanks, rings and bars to aerospace, helicopter-transmission and high-load-gear projects in India and worldwide, to AMS / EN 10084.

Why AISI 9310 / 14NiCrMo13-4 for Indian aerospace and gear projects

9310 is the standard aircraft-quality Ni-Cr-Mo gear steel high nickel for a tough core, deep hardenability, and a carburized case of 5862 HRC for contact-fatigue resistance, with VIM+VAR double-vacuum melting available for maximum fatigue life. For India's aerospace, defense and heavy-drivetrain sectors, it suits transmission and gearbox gears, high-load bearings and heavily loaded drive components.

Documented capability

Aerospace/helicopter transmissions: transmission gears, ring gears, pinions, gearbox gears.

High-load bearings: bearings and bearing races.

Shafts/drive components: heavily loaded shafts, drive components, defense drivetrain forgings.

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

Product range for Indian buyers

Forged aircraft and helicopter transmission gears, ring gears and pinions; turbine and accessory gearbox gears; high-load bearings and races; heavily loaded shafts and drive components; round/square/flat/rectangular bars; discs, hubs, sleeves.
