Common sheet metal materials

Dalian sheet metal parts widely used in the electronics industry include:

1. Ordinary cold-rolled plate SPCC

SPCC refers to the steel ingot through the cold rolling mill continuous rolling into the required thickness of steel coil or sheet material. SPCC surface without any protection, exposed to the air can be easily oxidized, especially in humid environments accelerated oxidation, the emergence of dark red rust, the use of the surface to paint, plating or other protection.

2. galvanized steel SECC

SECC substrate for the general cold-rolled coil, galvanized in the continuous galvanized line after degreasing, pickling, electroplating and various post-processing process, which became electrogalvanized products. SECC not only has the general cold-rolled steel mechanical properties and approximate processibility, but also has excellent corrosion resistance and decorative appearance. In the electronics, home appliances and furniture market has great competition and substitutability. For example, the computer chassis commonly used is SECC.

3. Hot dip galvanized steel SGCC

Hot-dip galvanized steel coil refers to the hot-rolled pickling or cold-rolled semi-finished products, after cleaning, annealing, immersed in a molten zinc bath temperature of about 460 ° C, and the steel plate coated with zinc, and then quenched Leveling and chemical treatment. The SGCC material is harder than the SECC material with poor ductility (avoiding deep draw design), a thicker zinc coating and poor weldability.

4.Stainless steel SUS301

Cr (chromium) content lower than SUS304, corrosion resistance is poor, but after cold work can get good tensile strength and hardness, better elasticity, and more for the leaf spring and anti-EMI.

5.Stainless steel SUS304

One of the most widely used stainless steels, due to Ni-containing steels, is more corrosion-resistant and heat-resistant than Cr-containing steels and possesses very good mechanical properties, no heat treatment, and no elasticity.
