What are the sheet metal materials? Come and have a look with me:
1. Ordinary cold rolled sheet SPCC
SPCC refers to the continuous rolling of steel ingots through cold rolling mills into steel coils or sheets of required thickness. There is no protection on the surface of SPCC, which is easily oxidized in the air. The unique feature is that the oxidation speed is accelerated in a humid environment, and dark red rust appears. The surface should be painted, electroplated or otherwise protected during use.
2. Galvanized steel sheet SECC
The substrate of SECC is ordinary cold-rolled steel coil, which becomes an electro-galvanized product after degreasing, pickling, electroplating and various post-treatment processes at the beginning and end of the continuous electro-galvanizing production line. SECC not only occupies the mechanical functions and similar processability of ordinary cold-rolled steel sheets, but also occupies excellent corrosion resistance and decorative appearance. It has great competitiveness and substitutability in the market of electronic products, home appliances and furniture. For example, SECC is widely used in computer cases.
3. Hot-dip galvanized steel sheet SGCC
Hot-dip galvanized steel coil refers to the semi-formed article after hot-rolling and pickling or cold-rolling, washed and annealed, immersed in a molten zinc tank at a temperature of about 460°C, and the steel sheet is coated with a zinc layer, and then subjected to It is made by tempering, leveling and chemical treatment. SGCC material is harder than SECC material, has poor ductility (design to prevent deep drawing), thicker zinc layer, and poor weldability.
4. Stainless steel SUS301
The content of Cr (chromium) is lower than that of SUS304, and the corrosion resistance is poor. However, cold working can achieve good tensile force and hardness from the beginning to the end, and the elasticity is better. It is mostly used for shrapnel springs and anti-EMI.
5. Stainless steel SUS304
It uses one of the most ordinary stainless steels. Because it contains Ni (nickel), it has better corrosion resistance and heat resistance than Cr (chromium) steel. It has quite good mechanical functions, no heat treatment is strong, and there is no elasticity.
The above is the sheet metal material, welcome everyone to consult and purchase.
