20CrMo 42CrMo 35CrMo 18CrNiMo7-6 Alloy Steel Forgings For Input Shaft Intermediate Gear Shaft
20CrMo 42CrMo 35CrMo 18CrNiMo7-6 Alloy Steel Forgings For Input Shaft Intermediate Gear Shaft
We specialize in the forging of high-performance alloy steel shafts, including input shafts and intermediate gear shafts, using premium grades such as 20CrMo, 42CrMo, 35CrMo, and 18CrNiMo7-6. These forged components are ideal for transmission systems requiring high strength, fatigue resistance, and dimensional stability under dynamic load conditions.
Material Grades:
-
20CrMo – Carburizing alloy steel with good hardenability, suitable for gears and transmission shafts requiring surface wear resistance and core toughness.
-
42CrMo – Widely used quenched and tempered alloy steel with excellent mechanical strength and impact resistance.
-
35CrMo – A medium carbon low-alloy steel with balanced toughness and strength, ideal for precision shafts.
-
18CrNiMo7-6 – Premium gear steel with deep hardenability, outstanding fatigue strength, and wear resistance after carburizing and hardening.
Product Scope:
-
Input shafts for gearboxes and drive assemblies
-
Intermediate gear shafts in power transmission systems
