Laser cutting of stainless steel is a widely used technology.

Stainless steel laser cutting is a very wide range of materials, especially in the medical industry, the cutting precision is very high. With a simple scanning system, a cutting speed of greater than 20 mm / min can be achieved with a good cut quality for a grade of 0.5 mm thick material. However, with a 40W HM laser, equipped with a fixed cutting head and coaxial auxiliary gas, the cutting speed on 200μm stainless steel can be greater than 1.5m / min!
Stainless steel laser cutting process with the carbon content of the corrosion resistance decreases, therefore, most of the carbon content of stainless steel are low, large not more than 1.2%, some steel Wc (carbon content) or even less than 0.03% (Such as 00Cr12). The main alloying element in stainless steel is Cr (chromium), only when the Cr content reaches a certain value, the steel has corrosion resistance. Therefore, stainless steel generally Cr (chromium) content of at least 10.5%. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si, Cu and other elements. Stainless steel often according to the organization state is divided into: martensitic steel, ferritic steel, austenitic steel, austenitic - ferritic (duplex) stainless steel and precipitation hardening stainless steel.
Stainless steel laser cutting technology is related to the optical, mechanical, electrical, materials and detection and other disciplines of a comprehensive technology, traditionally, its research can be divided into:
1. Laser processing system. Including lasers, light guide systems, machine tools, control systems and inspection systems.
2. Laser processing technology. Including cutting, welding, surface treatment, drilling, marking, marking, fine-tuning, and other processing technology
