Stainless steel SUS304: one of the most widely used stainless steel, because it contains Ni, it is richer than the steel containing Cr in corrosion resistance, heat resistance, has very good mechanical properties, no heat treatment hardening phenomenon, no elasticity.

Stainless steel SUS301: Cr content is lower than SUS304, corrosion resistance is poor, but after cold processing in the stamping process can obtain very good tensile strength and hardness, elasticity is better, mostly used for shrapnel springs and anti-EMI.

Ordinary cold rolled plate SPCC: SPCC refers to the ingot through the cold rolling mill continuous rolling into the required thickness of steel coil or sheet. SPCC exposed to air is very easy to be oxidized, especially in a humid environment oxidation speed up, the appearance of dark red rust, in use when the surface to paint, electroplating or other protection.

Hot-dip galvanized steel SGCC: Hot-dip galvanized steel coils are semi-finished products after hot-rolled pickling or cold-rolling, cleaned, annealed and immersed in a molten zinc bath at a temperature of about 460°C to coat the steel with a zinc layer, then tempered and leveled and chemically treated.

Galvanized Steel Sheet SECC: The substrate of SECC is a general cold rolled steel coil, which becomes a galvanized product after degreasing, pickling, plating and various post-treatment processes in a continuous galvanized production line, SECC not only has the mechanical properties and similar processability of a general cold rolled steel sheet, but also has superior corrosion resistance and decorative appearance. It is a competitive and alternative product in the market of electronic products, home appliances and furniture. For example, SECC is commonly used in computer cases.
