| Product Name | Forged Blank Shafts for Heavy Machinery with High Strength and Wear Resistance |
| Material Grade | - Premium alloy steels: 42CrMo, 42CrMo4, 18CrNiMo7-6 - Optimized for mechanical strength, toughness, and long-term wear resistance in heavy-duty machinery applications |
| Forging Equipment | - Hydraulic Open Die Hammers: 5T, 8T, 12T - Designed for forging medium-to-large shafts with uniform directional grain flow for enhanced fatigue performance |
| Manufacturing Process | Raw Material Inspection → Open Die Forging → Heat Treatment (Normalizing or Quenching + Tempering) → Rough or Precision Machining → Ultrasonic Testing (UT) → Dimensional Verification |
| Forging Ratio | ≥ 3.0 — Ensures consistent fiber alignment, superior stress distribution, and high durability under dynamic and cyclic loads |
| Applications | - Drive shafts, transmission shafts, and axles in heavy machinery - Hydraulic cylinder shafts and press machine spindles - Shafts for mining, construction, and port handling equipment |
| Heat Treatment Options | - Quenched + Tempered (Q+T): Maximum strength and wear resistance for finished shafts - Normalized + Tempered (N+T): For semi-finished shafts ready for further machining |
| Testing & Inspection | - Chemical Analysis: Spectrometry-certified - Mechanical Tests: Tensile, Impact, Hardness - Ultrasonic Testing (UT): Internal soundness check - Dimensional Control: Outer/inner diameters, concentricity, straightness - Metallography: Grain structure and heat treatment validation |
| Value-Added Services | - Machined bores, keyways, splines per drawing - Anti-corrosion and export-ready packaging - Support for DDP or CIF delivery to global heavy machinery sites |
The steel forging manufacturing process follows a strict sequence:
incoming material inspection → unloading → quality verification → preheating → forging → heat treatment → intermediate inspection → rough machining → non-destructive testing → final inspection → packaging → shipment.
