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.
These discs are vital for high-stress applications in:

|---|---|
| Product Name | 20CrMnMo 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 Process | Hot 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 |
| Applications | Heavy 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 |
