| Product Name | Customized 42CrMo Forged Blank for Ship-to-Shore Crane Wheels, Trolleys |
| Material Grade | - High-performance alloy steel: 42CrMo (AISI 4140 equivalent)- Exceptional balance of strength, impact resistance, and surface hardness- Tailored for frequent start-stop, directional reversal, and heavy brake load environments |
| Forging Equipment | - Hydraulic Open Die Hammers: 5T, 8T, 12T- Optimized for medium-to-large forged rings and wheel blanks used in STS trolley running systems |
| Manufacturing Process | Billet Inspection → Open Die Forging → Normalizing or Quenching + Tempering → Rough or Precision Machining → Ultrasonic & Dimensional Inspection |
| Forging Ratio | ≥ 3.0 – Ensures directional fiber alignment, improved stress distribution, and high durability under dynamic crane loading cycles |
| Applications | Specifically engineered for:- Ship-to-shore crane trolley wheels and drive wheel hubs- Rail-mounted gantry crane rollers and guide wheel blanks- Suitable for high-duty port operations, including automated container terminals and shipyard gantry systems |
| Heat Treatment Options | - Quenched + Tempered (Q+T): For maximum strength and wear resistance in final-machined components- Normalized + Tempered (N+T): For semi-finished parts with machining allowance |
| Testing & Inspection | - Chemical Analysis: Spectrometer-certified- Mechanical Tests: Tensile, impact, and hardness- Ultrasonic Testing (UT): Internal integrity validation- Dimensional Control: Gauge-based verification of outer/inner diameters, concentricity, and roundness- Metallography: Grain refinement and heat treatment quality check |
| Value-Added Services | - Machined profiles for bores, flanges, and keyways available per drawing- Anti-corrosion packaging and export-ready crate solutions- Support for DDP or CIF delivery to port and shipyard locations globally |
