| 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 |
