Best Steel for Laser Cutting Guide
The best steel for laser cutting transforms stubborn metal sheets into aerospace components with micron precision, carves architectural masterpieces overnight, and turns prototyping chaos into production-line perfection. One miscalculation in material selection, однако, can trigger catastrophic warping, ragged edges, or financial hemorrhage from wasted resources. Forget generic charts – this is your tactical metallurgical playbook.
The Steel Selection Battlefield
Metallurgical Combat Zones
- Carbon Steel Frontline(Low/Medium Carbon):
- Advantage: Cost-efficient cutting at 6-12m/min (1мм)
- Threat: Oxide dross buildup beyond 15mm thickness
- Critical Spec: 0.3% max carbon content for clean edges
2. Stainless Steel Theater(304/316):
- Beam Engagement: Requires nitrogen assist gas
- Speed Trap: 40% slower than carbon steel
- Victory Condition: RA<1.5µm surface finish
3. Alloy Steel Recon(4140/Tool Steel):
- Covert Ops: Pre-heating to 200°C prevents cracking
- Lethal Threshold: >0.5% chromium demands power adjustment
