Product details

Forged Gear Ring Blanks in 18CrNiMo7-6 Alloy Steel

Jiangyin Fangyuan delivers precision-forged gear ring blanks crafted from premium 18CrNiMo7-6 alloy steel, engineered for critical applications in wind energy, heavy machinery, and industrial transmission systems. Manufactured from high-purity continuous-cast rounds or ingots, our forgings guarantee exceptional metallurgical integrity, fatigue resistance, and load-bearing capacity—ensuring reliability in the most demanding environments.

Key Features

Superior Material Quality:

Forged from 18CrNiMo7-6 alloy steel (equivalent to ISO 683-1/EN 10084), optimized for high core toughness (impact energy ≥60J at -20°C) and surface hardness (HRC 58-62 post-carburizing).

Continuous-cast inputs ensure minimal segregation and uniform grain flow.

Advanced Forging Process:

Closed-die forging enhances grain structure, eliminating voids/inclusions and improving fatigue strength by 30% vs. cast alternatives.

Precision-machined pre-forms reduce post-forging machining costs.

Thermal Management:

Custom heat treatment (carburizing, quenching, tempering) tailors hardness depth (CHD: 1.5–5mm) for optimal pitting resistance.
