Common materials for sheet metal fabrication.
1. Galvanized steel sheet SECC made of sheet metal fabrication
The substrate of SECC made of sheet metal fabrication is a general cold-rolled steel coil, which becomes an electro-galvanized product after degreasing, pickling, electroplating and various post-treatment processes in a continuous electro-galvanizing production line. SECC made of sheet metal fabrication not only has the mechanical properties and similar processability of ordinary cold-rolled steel sheets, but also has superior corrosion resistance and decorative appearance. It has great competition and substitution in the market of electronic products, home appliances and furniture. For example, the commonly used computer case is SECC.
2. Ordinary cold rolled sheet SPCC made of sheet metal fabrication
Sheet metal fabrication SPCC refers to the continuous rolling of steel ingots into steel coils or sheets of required thickness through a cold rolling mill. The surface of the SPCC made of sheet metal fabrication does not have any protection, and it is easily oxidized when exposed to the air. Especially in a humid environment, the oxidation speed is accelerated, and dark red rust appears. The surface should be painted, electroplated or otherwise protected when used.
3. Hot-dip galvanized steel sheet SGCC made of sheet metal fabrication
The hot-dip galvanized steel coil made of sheet metal fabrication refers to the semi-finished product after hot-rolling pickling or cold-rolling, after cleaning, annealing, and immersing it in a molten zinc bath with a temperature of about 460 ° C, so that the steel sheet is plated with a zinc layer, It is then tempered, leveled and chemically treated. SGCC material made of sheet metal fabrication is harder than SECC material, has poor ductility (avoid deep drawing design), thicker zinc layer and poor weldability.
4. Sheet metal fabrication made of stainless steel SUS304
It is one of the most widely used stainless steels in sheet metal fabrication. It contains Ni (nickel), so it is more resistant to corrosion and heat than steel containing Cr (chromium). It has very good mechanical properties, no heat treatment hardening phenomenon, and no elasticity. .
5. Stainless steel SUS301 made of sheet metal fabrication
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 shrapnel springs and anti-EMI.
