Metal Shear Capabilities for High-Strength Steel
Equipment Requirements
- Hydraulic shears preferred for high cutting forces (1000+ tons)
- Can process AHSS and quenched/tempered steels up to 50mm thick
- Mechanical shears may lack sufficient force for highest-strength alloys
Blade Specifications
- Materials: Tungsten carbide or high-speed steel for wear resistance
- Optimal clearance: 5-10% of material thickness
- Precision angles reduce burring and edge defects
Process Optimization
| Factor | Consideration |
|---|---|
| Pre-heating | Reduces material hardness for easier cutting |
| Cutting speed | Balances blade wear vs. work-hardening risks |
| Lubrication | Reduces friction and heat generation |
Performance Limitations
- Steels above 1,500 MPa yield strength may require alternatives
- Extreme hardness can cause premature blade wear
- Consider laser or waterjet cutting for toughest alloys
Industry Application:
Successfully used in automotive (frame components), aerospace (structural parts), and construction (support beams)
