High Light 20crmo steel forging blanksteel forged blanks rough machined40crnimo steel forged blanks

42CrMo4,20CrMo,40CrNiMo Steel Forged Blanks Supplied in As-Forged or Rough-Machined Condition for Industrial Use. The 42CrMo4, 20CrMo, and 40CrNiMo steel forging billets we supply are designed to meet stringent industrial needs and can be provided in forged or rough-processed states. With excellent material properties and flexible delivery forms, they provide a solid foundation for industries such as machinery manufacturing, energy, mining and metallurgy.

Product Features

  • Premium Alloy Steels: Uses 42CrMo4, 20CrMo, 40CrNiMo for exceptional strength, toughness, and hardenability.
  • Superior Internal Structure: Forging refines grain, boosting ductility, fatigue resistance, and structural integrity.
  • Flexible Supply: Available as-forged or rough-machined to suit your processing needs.
  • Enhanced Mechanicals: Forging improves tensile strength, yield strength, impact resistance, and wear characteristics.
  • Excellent Heat Treatability: These alloys respond well to various heat treatments for customized properties.
  • Customizable: Offered in diverse dimensions and weights to meet specific component requirements.

Application Scenarios

These alloy steel forged blanks are essential for high-performance parts across heavy industries:

  • Power Transmission: For gears, shafts, and couplings in industrial gearboxes, wind turbines, and marine propulsion.
  • Heavy Machinery: Used in axles, pins, and linkages for excavators, cranes, and mining equipment.
  • Oil & Gas: Suitable for valve bodies, wellhead components, and pump parts under high pressure and loads.
  • Metallurgical Equipment: Blanks for rollers, shafts, and other stressed parts in steel mills.
  • General Industrial: Components for presses, hammers, and heavy pumps needing durable forged parts.

Product Name
42CrMo4,20CrMo,40CrNiMo Steel Forged Blanks Supplied in As-Forged or Rough-Machined Condition for Industrial Use
Material Grades
- Our primary alloy is 42CrMo4, a high-performance steel renowned for its exceptional strength, superior toughness, and outstanding resistance to wear. Specifically chosen for demanding applications, it excels in metallurgical equipment components facing heavy loads and significant stress.
Forging Equipment
- Hydraulic hammers: 5T / 8T / 12T- Large open-die forging press with core boring capability- Near-net shape forging for components with complex geometries
Manufacturing Process
Hot Forging → Intermediate Heat Treatment → Optional Core Boring / Drilling →Rough / Semi-Finish Machining → UT & Dimensional Inspection
Forging Ratio
≥ 3.0 — Promotes directional grain flow, ensuring excellent load-bearing capacity and fatigue resistance in metallurgical applications
Applications
- Components in steelmaking equipment: furnace shells, trunnions- Parts of continuous casting equipment: mold, vibration device- Elements of steel rolling equipment: mill housings, rolls- Components of metallurgical cranes: bridge, drum, hook
Heat Treatment Options
- Normalizing and tempering for enhanced mechanical properties- Stress relief treatment to ensure dimensional stability
Testing & Inspection
- Chemical: Spectrometer-controlled composition analysis- Mechanical: Hardness, tensile, yield, impact toughness- Ultrasonic (UT): Multi-angle flaw detection, including bore zone- Dimensional: Length, diameter, straightness, concentricity
Value-Added Services
- We deliver components with tailored geometries to flawlessly integrate with your metallurgical equipment. Every piece arrives with pre-machined surfaces for quick, seamless assembly, and is laser-marked for clear identification and complete lifecycle traceability.

The steel forgings production flow:

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