Selection of sheet metal processing materials

Selection of sheet metal processing materials

Sheet metal processing parts are common structural parts that can be widely used in many fields. The main processing methods for sheet metal parts are welding and laser cutting, which have the advantages of light weight, good rigidity and high precision. The thickness of sheet metal parts is generally less than 6mm, and various shapes of parts can be made through a variety of cold processing processes. After cold processing of sheet metal, the thickness of sheet metal parts can be changed to a more fixed thickness. However, due to the different uses of sheet metal, different sheet metal materials need to be selected.

Generally, sheet metal processing materials are mainly divided into the following types: stainless steel, copper, aluminum and other materials. Different types of sheet metal materials require different processing methods and different methods.

1.1 Stainless steel plate.

(1) Cold rolled steel plate. Cold rolled steel plate is a steel plate that is controlled at room temperature below the recrystallization temperature and then rolled to become thinner. Among cold rolled steel plates. Its surface is smooth, the thickness is uniform, it does not incur a large cost, and it is easy to form. It can be painted or electroplated to expand the application range of steel plates. (2) Hot-rolled steel plate: This steel plate processing method mainly processes the raw rolled plate or ingot, heats it, and then dephosphorizes it to form the rough rolled steel plate. Generally, the thickness of the hot rolled steel plate will have slight deviations, and folding problems may occur during actual processing. Hot rolled steel plate processing technology is mainly used to produce parts for automobiles, bridges, ships and other equipment.

1.2 Galvanized steel plate.

Galvanized steel plate is mainly galvanized on the surface of the steel plate. Under normal circumstances, the thickness of the galvanized layer of the steel plate needs to be controlled at more than 10μm to prevent corrosion and other damage on the surface of the steel plate. This is mainly because the corrosion protection requirements are very high when used in parts.
