Main use of stainless steel (stainless acid-resistant steel) sheet metal processing:

There are many sheet metal materials suitable for stamping processing. The sheet metal materials commonly used in the electrical and electronic industry include:

 1. General Cold Rolled Sheet SPCC SPCC refers to the continuous rolling of steel ingots into coils or sheets of the required thickness by a cold rolling mill. SPCC has no external protection. It is easily oxidized when exposed to air, especially in a humid environment. It has a dark red rust and should be painted, plated or otherwise protected during use.

 2. Definition: The welded steel sheet with hot-dip or electro-galvanized layer on the surface is SECC SECC. The substrate is a general cold-rolled steel coil. After the continuous electro-galvanizing line is degreased, pickled, electroplated and various post-treatment processes, That is to become an electro-galvanized product. Sheet metal processing is a key skill for the needs of sheet metal skill personnel and an important process for the formation of sheet metal products. It not only includes traditional cutting, blanking, bending and forming methods and process parameters, but also includes various cold stamping die structures and process parameters, various equipment operating principles and operating methods, as well as new stamping skills and New Technology. SECC not only has the mechanical properties and approximate processability of general cold-rolled steel sheets, but also has excellent corrosion resistance and decorative appearance. It is highly competitive and alternative in the market of electronic products, home appliances and furniture. For example, the SECC is commonly used in computer cases.

 3. Hot dip definition: welded steel plate with hot dip or electrogalvanized layer. SGCC hot dip galvanized steel coil refers to the semi-finished product after hot rolling pickling or cold rolling. It is cleaned and annealed and immersed at a temperature of about 460 ° C. In the molten zinc bath, the steel sheet is plated with a zinc layer, and then quenched and tempered and chemically treated. The SGCC data is harder and less ductile than the SECC data (to avoid deep pumping planning), the zinc layer is thicker, and the weldability is poor.

 4, stainless steel (stainless acid steel) SUS301 (permanent redirection) Cr (chromium) contains a lower specific gravity than SUS304, corrosion resistance is poor, but through cold processing can achieve good tensile and hardness, good elasticity, more used Shrapnel springs and EMI protection. Shanghai Sheet Metal has the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, and large-scale mass production performance. It is widely used in the fields of electronics, telecommunications, automotive industry, medical equipment, etc. In computer cases, mobile phones, and MP3s, sheet metal is an essential part. The processing of Gusu chassis is the key skill for the needs of sheet metal skill personnel, and it is also an important process for the formation of sheet metal products. It not only includes traditional cutting, blanking, bending and forming methods and process parameters, but also includes various cold stamping die structures and process parameters, various equipment operating principles and operating methods, as well as new stamping skills and New Technology.

 5, stainless steel (stainless acid-resistant steel) SUS304 One of the most widely used stainless steel (stainless acid-resistant steel), because it contains Ni (nickel), it is more corrosion-resistant and heat-resistant than steel containing Cr (chromium). Very good mechanical properties, no heat treatment (chǔ lǐ) hardening, no elasticity.
