40CrNiMo, C45, 42CrMo Custom Heavy Steel Forgings for Industrial,Power Use. This series of forgings are made of 40CrNiMo, C45, 42CrMo high-performance steel, and are precisely formed through free forging/die forging processes, and are equipped with heat treatment technologies such as quenching and tempering, normalizing, and surface strengthening.
They are specially designed to provide high-strength, wear-resistant, and long-life core component solutions for heavy machinery transmission systems, generator rotors, and high-load industrial equipment.

| Product Name | 40CrNiMo, C45, 42CrMo Custom Heavy Steel Forgings for Industrial,Power Use |
| Material Grades | - Medium/high-carbon and alloy steels designed for structural integrity- Customized steel compositions for static and dynamic heavy-load conditions |
| Forging Equipment | - Hydraulic Presses: 5T, 8T, 12T- Capable of producing large cross-section forged blocks with uniform grain flow |
| Manufacturing Process | Raw Material Inspection → Preheating → Open Die Forging → Heat Treatment → Rough Machining → Non-Destructive Testing → Final Machining (if required) → Dimensional Inspection → Packaging |
| Forging Ratio | ≥ 3.0 — Enhances internal grain density and resists deformation under high-pressure loads |
| Applications | - Structural bases for crushers and presses- Machine bed blocks for rolling mills- Frame blocks for large gear housings- Mounting blocks for heavy hydraulic assemblies |
| Delivery Conditions | - Delivered in heat-treated condition- Optional: As-forged, stress-relieved, or semi-machined states available |
| Testing & Inspection | - Chemical Analysis (Optical Spectrometry)- Mechanical Testing: Tensile, Hardness- Non-Destructive Testing: Ultrasonic Testing (UT), Magnetic Particle Testing (MT)- Dimensional Inspection |
Process flow:
raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
