Plasma cutting has a wide range of applications. With different working gas, it can cut various kinds of metals that are difficulty to handle by oxygen cutting. Plasma cutting is fast and efficient when cutting metal with small thickness. The EN10025-4 S420M steel cutting speed can reach more than 10m/min. Plasma cutting can get a clean, neat, non stick slag cutting surface, while the deformation and thermal effect of the incision are small, its hardness change is little, and the cutting quality is good.

The basic principle of EN10025-4 S420M steel, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the EN10025-4 S420M steel principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
