| Item | Details |
| 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.
