42CrMo 40Cr Forged Gear Precision Forged Alloy For Wind Power Gearbox

42CrMo/40Cr Precision Forged Gear for Wind Power Gearbox and Construction Equipment.

Looking for high-performance forged gears for wind turbine gearboxes or industrial reducers? Our precision forged gears, manufactured from premium 42CrMo and 40Cr alloy steels, deliver exceptional strength, toughness, and long service life under extreme load and rotational stress conditions. With over 25 years of forging expertise, we supply top-quality transmission components for the renewable energy, port machinery, and heavy industrial sectors.

High-Performance Forged Gears for Wind Energy Applications
Our forged gears are widely used in wind power gearbox systems, especially in high-load planetary and helical gear stages. 42CrMo4 and 40Cr alloy steels are selected for their superior mechanical performance after quenching and tempering treatment, offering:

High tensile and yield strength

Excellent impact toughness

Superior wear and fatigue resistance

Enhanced hardenability and stability

These properties make our gears particularly suitable for offshore and onshore wind turbines, where components must withstand fluctuating loads, temperature variations, and long-term vibration.
