42CrMo4 stress-relieved alloy steel forgings are engineered for demanding metallurgical machinery applications that require high tensile strength, toughness, and dimensional stability. These forgings are manufactured using open-die forging techniques and subjected to precision-controlled stress-relief heat treatment to minimize residual stress, distortion, and cracking during subsequent machining or service.
With excellent hardenability and fatigue resistance, 42CrMo4 alloy steel is well-suited for components exposed to high loads, fluctuating temperatures, and cyclic forces. These forgings are commonly used in rolling mill drive components, furnace lifting mechanisms, press columns, gear shafts, and other high-load bearing structures in the metallurgical industry.
Machined to customer specifications and rigorously inspected, our 42CrMo4 forgings offer enhanced internal soundness, grain refinement, and reliable performance in continuous-duty steelmaking and metal forming environments.

| Product Name | 42CrMo4 Stress-Relieved Alloy Steel Forgings for Metallurgical Equipment |
| Material Grades | - Primary alloy: 42CrMo4- High strength, excellent toughness, and superior wear resistance- Engineered for metallurgical equipment components under heavy loads and high 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 | - Custom geometries for specific metallurgical equipment needs- Pre-machined surfaces for easy integration into equipment- Laser part marking and full traceability |
The steel forgings production flow:
raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
