For cutting 11–20mm stainless stainless steel with production-quality edges, a 6–12kW fiber laser is recommended for consistent quality. Nitrogen assist gas (10–20 bar pressure) is the standard choice for stainless steel cutting to prevent oxidation and achieve shiny, oxide-free edges suitable for food-grade, pharmaceutical, and architectural applications. Higher laser power improves both speed and edge quality on stainless by maintaining a cleaner melt pool ejection. Our 59 listed machines all meet or exceed the power requirements for this thickness range.
Nitrogen is strongly preferred for stainless steel cutting in most applications. Benefits include: bright, oxide-free edges that require no post-processing, no discoloration or heat tinting, and suitability for food-grade, pharmaceutical, and decorative applications. Nitrogen cutting requires higher laser power (approximately 2× vs. oxygen) but eliminates secondary finishing operations. Oxygen can be used for thicker sections (20mm+) where nitrogen cutting becomes impractical due to power requirements, but produces a dark oxide layer that must be removed for most applications. High-pressure nitrogen (15–20 bar) with a large-diameter nozzle (2–3mm) delivers the best results for production cutting.
