1. Galvanized steel sheet SECC
The substrate of SECC is a common cold-rolled steel coil, which becomes an electro-galvanized product after degreasing, pickling, electroplating and various post-treatment processes in the continuous electro-galvanized production line. SECC not only has the mechanical properties and approximate workability of general cold-rolled steel sheets, but also has excellent corrosion resistance and decorative appearance. In the electronic products, home appliances and furniture market has a great competitive and alternative. For example, computer chassis is commonly used in SECC.
2. Ordinary cold rolled sheet SPCC
SPCC refers to the steel ingot through the cold rolling mill continuously rolled into the required thickness of the steel plate coil or sheet. SPCC surface without any protection, exposed to the air is very easy to be oxidized, especially in a humid environment, the oxidation rate is accelerated, dark red rust, in the use of the surface to paint, electroplating or other protection.
3. Hot-dip galvanized steel sheet SGCC
Hot-dip galvanized steel coil refers to the semi-finished products after hot-rolled, pickled or cold-rolled, cleaned, annealed, immersed in a molten zinc bath with a temperature of about 460°C, so that the steel sheet is plated with a zinc layer, and then tempered and leveled and chemically treated. SGCC material is harder than SECC material, poor ductility (avoid deep drawing design), thicker zinc layer and poor electric weldability.
4. Stainless steel SUS304
One of the widely used stainless steel, because of containing Ni (nickel), it is richer than Cr (chromium) steel corrosion resistance, heat resistance, has very good mechanical properties, no heat treatment hardening phenomenon, no elasticity.
5. Stainless steel SUS301
The content of Cr (chromium) is lower than that of SUS304, and the corrosion resistance is poor, but after cold working, it can obtain good tensile force and hardness in stamping processing, and has good elasticity. It is mostly used for elastic spring and EMI prevention.
