Q620D steel plate cutting process
After the factory inspection of Q620D steel plate, the performance indicators meet the requirements, and the cutting process can be carried out. It can be cut and processed. Generally, when the thickness of the steel plate is not greater than 20mm, it is preferred to use CNC plasma cutting or CNC laser cutting. If the thickness of the steel plate is greater than 30mm or more , usually choose CNC flame cutting, which can control the cutting accuracy and time.
Q620D steel plate application range
Q620D steel plate is mainly used in drilling rigs, electric shovels, electric wheel dump trucks, mining cars, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports, heavy vehicles, construction machinery, etc. Structural parts and mechanical equipment.
