|---|---|
| Product Name | Rough Forged Carbon Steel 35# / 45# Wheel Blank – OEM Supplier |
| Material Grades | - High-strength carbon steels: 35# and 45# - Excellent wear resistance and good machinability - Suitable for impact-loaded and friction-prone wheel applications |
| Forging Equipment | - Hydraulic forging hammers: 5T / 8T / 12T - Optimized for solid wheel blanks and flanged wheel forgings - Ensures uniform deformation and enhanced grain flow |
| Manufacturing Process | Hot Forging → Normalizing (optional) → Rough Machining → Pre-machining / Heat Treatment → Dimensional Inspection |
| Forging Ratio | ≥ 3.0 — Promotes optimal metal flow from hub to rim, improving fatigue resistance and internal stress distribution |
| Applications | - Crane wheels, port machinery wheels, and mining transport wheels - Railway wheels and rolling mill drive wheels - Designed for cyclical loads, radial/axial forces, and rolling fatigue |
| Heat Treatment Options | - Normalized, or Quenched + Tempered as required - Optional stress-relief treatment before final machining |
| Testing & Inspection | - Chemical: Spectrometer alloy analysis - Mechanical: Hardness, tensile, impact testing - Ultrasonic: UT scanning focused on wheel hub integrity - Dimensional: OD, ID, thickness, run-out |
| Value-Added Services | - Custom diameter, hub, and rim profiles - Optional rough or pre-machining - Protective coating, export packaging, part labeling - OEM branding and marine shipment preparation available |
