What are the common materials for sheet metal shell processing?

　　The common materials for sheet metal shell processing are as follows:

　　1. General cold-rolled thin plate SPCC

　　SPCC refers to the use of a cold rolling mill to continuously cold-roll steel castings into hot-rolled strips or thick steel plates of the required thickness. SPCC has no surface protection. When exposed to air, it is easily oxidized, especially in humid conditions, the oxidation rate is accelerated, and dark red rust is generated. The surface of the sheet metal shell should be sprayed, electroplated or otherwise protected during the production process.

　　2. Stainless steel plate SUS301

　　The chromium content is lower than SUS304, and the corrosion resistance is poor. However, after cold drawing, the sheet metal shell can obtain better tensile strength and strength during the die-casting process, and has better ductility. Suitable for spring plate torsion spring and interference signal protection.

　　3. Hot-dip galvanized steel plate SGCC

　　Hot-dip galvanized coil steel is a semi-finished coil steel processed by hot rolling, pickling passivation or hot rolling. After cleaning and quenching, the thick steel plate is immersed in 460℃ zinc liquid, coated with zinc layer, and then heat treated, quenched, and corrected chemical treatment.

　　IV. Stainless steel plate SUS304

　　Stainless steel plate is a kind of steel commonly used in sheet metal shells. Due to its nickel content, its corrosion resistance and temperature resistance are better than manganese-containing steel. Therefore, it can have better physical properties, no heat treatment hardening, and no elasticity.

　　V. Galvanized sheet

　　After degreasing, pickling passivation, electroplating and various post-processing on the continuous electrogalvanizing production line, the high-precision sheet metal shell becomes a phosphating product. SECC not only has the physical properties and similar production characteristics of ordinary cold-rolled plates, but also has good corrosion resistance and decorative appearance. Sheet metal chassis processing has extremely competitive and substitutable in the electronic equipment, electrical appliances and home markets.

　　To sum up, we can see that the common materials for sheet metal shell processing are cold-rolled thin plates SPCC, stainless steel plates SUS301, hot-dip galvanized steel plates SGCC, stainless steel plates SUS304, galvanized plates... and so on. Since different sheet metal shell processing materials have different functions, when choosing sheet metal shells, you also need to choose suitable materials from the perspective of product, usage and consumption cost. In this way, the manufactured sheet metal shell processing products can meet your needs.
