High Torque Carbon Steel Forgings ISO9001 Input Shaft Forgings For Power Transmission Systems

High-Torque Carbon Steel Input Shaft Forgings for Power Transmission Systems

High-Torque Carbon Steel Input Shaft Forgings are core drivetrain components engineered to transmit initial mechanical power in industrial systems. Manufactured from medium-carbon steel (e.g., 1045, C45) via precision open-die forging, these shafts deliver exceptional torsional strength and fatigue resistance for high-load startup conditions.

Key Characteristics

1. Optimized Torsional Rigidity

   • Directional grain flow aligns with shaft axis, maximizing torque capacity.

2. Superior Impact Absorption

   • Withstands sudden load spikes during equipment startup.

3. Controlled Machining Allowance

   • Near-net shape

4. Uniform Hardness Profile

   • Heat treatment ensures consistent properties through cross-sections

Primary Applications

The steel forgings production flow:

raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
