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.

Features

  • Multi - material choice: 40CrNiMo for high strength, C45 for cost - effective machining, 42CrMo for top - notch mechanicals.
  • Tailored production: According to customer requirements, forging is carried out strictly according to the drawings
  • Precision processes: Forging ratio 3:1; strict heat treatment.
  • Rigorous checks: Chemical analysis, ultrasonic flaw detection; key specs .

Advantages

  • Top - tier performance: Handles high stress, extreme conditions; long service life.
  • Cost - efficient: Smart material use, low maintenance costs.
  • Quality - assured: Comply with standards
  • Full - service: Expert - led support from design to delivery.

Applications

  • Industry: Machinery parts (gears, shafts), petrochemical high - pressure components, mining wear - resistant parts.
  • Power: Generator rotors, transmission tower connectors, ensuring power system reliability.
Item Details
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.

Frequently Asked Questions (FAQs)
