    20CrMnMo 42CrMo4 Forged Disc Heavy Duty Industrial Alloy Steel CNC Forgings

    20CrMnMo 42CrMo4 Heavy Duty Industrial Alloy Steel Forgings Disc. Our heavy-duty industrial alloy steel forging discs are made from high-grade 20CrMnMo and 42CrMo4 steels. Forging enhances their strength, toughness, and fatigue resistance by refining the grain structure and eliminating defects. These discs are ideal for critical load-bearing and rotational applications, serving as blanks for gears, flanges, and other high-performance components.


    Key Features

    • Premium Alloy Steels:
      • 20CrMnMo: High strength, excellent hardenability, and toughness, good for case hardening.
      • 42CrMo4: Outstanding tensile strength, wear, and impact resistance after heat treatment.
    • Superior Properties: Forging delivers high strength, impact resistance, and long fatigue life.
    • Extreme Durability: Built to withstand high pressures, temperatures, and abrasive conditions.
    • Optimized Structure: Refined grain ensures consistent quality and prevents stress points.
    • Versatile Form: Perfect as blanks for large gears, rings, flanges, and rollers.

    Application Areas

    These discs are vital for high-stress applications in:

    • Heavy Machinery: Gears, bearings, rollers for construction and mining.
    • Power Generation: Turbine parts, couplings, large flanges.
    • Oil & Gas: High-pressure flanges, valve components.
    • Marine & Shipbuilding: Propeller shafts, large gear blanks.
    • Industrial Transmission: Large gear blanks, shafts.
    ItemDetails
    Product Name20CrMnMo 42CrMo4 Heavy Duty Industrial Alloy Steel Forgings Disc
    Material Grades- Alloy steels suitable for boring and rotary stress resistance: e.g., 42CrMo4, 18CrNiMo7-6 - Excellent machinability and impact absorption - Specifically adapted for inner bore formation while retaining high outer wall strength
    Forging Equipment- Hydraulic Hammers: 5T, 8T, 12T capacity - Configured for forging of bored shafts, thick-wall rings, and tubular blanks - Enables near-net shape forging with axial bore requirements
    Manufacturing ProcessHot Forging → Thermal Refinement → Boring / Core Machining → Rough or Precision Machining → Dimensional & Integrity Evaluation
    Forging Ratio≥ 3.0 — Delivers improved fiber orientation along the rotational axis, minimizing internal defects and optimizing rotational balance under dynamic stress
    ApplicationsHeavy Duty Industrial
    Heat Treatment Options- Normalized + Tempered based on strength requirements - Intermediate stress relieving available prior to final machining
    Testing & Inspection- Chemical Composition: Spectrometer validation for alloy uniformity - Mechanical Properties: Hardness profiling, tensile, and impact strength - Ultrasonic Examination: Multi-angle UT scanning for hollow bore consistency - Dimensional Testing: Bore tolerance, straightness, wall thickness verification
    Value-Added Services- Custom boring diameter, length, and wall profile options - Pre-machined surfaces, protective packaging, anti-corrosion measures - Support for export handling, part labeling, and marine-ready logistics


    The steel forgings production flow:

    Raw material steel ingot into warehouse(test the chemical composition) → Cutting→ Heating(Furnace temperature test) → Heat treatment after forging(Furnace temperature test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal dimension, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment.
