| Product Name | Custom-Sized High-Strength Carbon Steel Forging Blank for Mechanical Parts |
| Material Grades | - High-strength carbon steels: 35#, 45#, customized grades available - Excellent tensile strength, impact toughness, and fatigue resistance - Designed for solid or hollow-core mechanical components under dynamic stress |
| Forging Equipment | - Hydraulic hammers: 5T / 8T / 12T - Large open-die forging press with optional core boring - Supports near-net shape forging with or without internal cavities |
| 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, improves fatigue life and mechanical integrity |
| Applications | - Gear shafts, coupling blanks, wheels, and structural parts - Applied in heavy machinery, power transmission, and general mechanical assemblies - Capable of handling impact loads, torque, and fluctuating forces |
| Heat Treatment Options | - Quenched + Tempered for strength and toughness - Optional stress relief to enhance dimensional stability |
| Testing & Inspection | - Chemical: Spectrometer-controlled composition analysis - Mechanical: Hardness, tensile, yield, impact toughness - Ultrasonic (UT): Multi-angle flaw detection, including bore zone (if applicable) - Dimensional: Diameter, length, flatness, straightness, concentricity |
| Value-Added Services | - Custom geometry: bore size, wall thickness, external profiles - Pre-machined ends, grooves, or journals - Rust protection, end caps, steel banding & wooden crate packing - Laser ID marking, OEM branding, full part traceability |
The steel forgings production flow:
raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
