Oxygen (O2 = 100%) is suitable for low alloy steel products. Stainless steel is not cut due to solid chromium carbide inclusions in the cutting area. In this case, laser welding and cutting is probably the most promising metalworking technology these days. Laser cutting makes it possible to separate metal in a more straightforward and narrow manner compared to plasma cutting. It is laser cutting that results in a cleaner and smoother cut that does not require further refinement.
