How To Choose Sheet Metal Fabrication Materials?
The raw materials generally used in Sheet Metal Fabrication include cold-rolled steel sheets, hot-rolled steel sheets, galvanized steel sheets, copper copper, red copper, beryllium copper, aluminum alloy sheets, and stainless steel. The main purpose and cost will be taken into consideration. Sheet metal processing is the core technology that sheet metal technical staff must master, and it is also the key process for forming sheet metal handicrafts. Sheet metal processing includes traditional laser cutting, cold stamping processing, bending forming and other methods and process parameters, as well as various cold stamping die structures and process parameters, various machines The equipment principle and control method also include new stamping die technology and new technology and new process. The production and processing of sheet metal materials for parts is called sheet metal processing. So, how to choose sheet metal processing materials?
1. Galvanized sheet
The substrate of galvanized sheet is ordinary cold-rolled steel coil, which becomes a phosphating product after degreasing, pickling passivation, electroplating and various post-treatment processes in the continuous phosphating production line. It not only has the physical properties and similar technological properties of general cold-rolled steel sheets, but also has excellent corrosion resistance and decorative artistic appearance. There is considerable competition and substitution in the sales market of electronic equipment, household appliances and furniture.
2. General cold-rolled steel plate
Cold-rolled steel plate refers to steel castings that are continuously cold-rolled by a cold-rolling mill into thick steel tubes or trims of specified thickness. There is no protection on the surface, and it is easily oxidized when exposed to air, especially in a humid environment, the oxidation rate is accelerated, and dark red rust appears. The surface needs to be sprayed, electroplated or otherwise protected during use.
3. Hot-dip galvanized thick steel plate
Hot-dip galvanized coil steel refers to the processing of semi-finished products after hot-rolling, pickling, passivation or cold-rolling. After cleaning and quenching, they are infiltrated into a molten zinc bath at a temperature of about 460°C, and then the steel plate is inlaid with a zinc layer, and then heat-treated. Leveling and organic chemical solution. The raw material is harder than the raw material, the plasticity is poor, the zinc layer is thicker, and the arc welding ability is poor.
4. 304 stainless steel
One of the most widely used stainless steels, it is often made into Bending Parts. Because it contains nickel, it is more corrosion-resistant and temperature-resistant than steel containing chromium, and has good physical properties. malleability.
5. 301 stainless steel
The content of chromium is lower than that of 304, and its corrosion resistance is weaker, but after cold drawing, it can obtain good tensile strength and strength in stamping processing, and has good elasticity. It is mostly used for spring springs and anti-EMI.
