SECC's substrate is a general cold rolled steel coil, which becomes an electrogalvanized product after going through degreasing, pickling, plating, and various post-processing in a continuous electrogalvanized line.SECC not only has the mechanical properties of a general cold rolled steel sheet and its similar processability, but also has a superior corrosion resistance and decorative appearance. In the market of electronic products, home appliances and furniture, SECC has great competitiveness and substitutability. For example, computer chassis commonly used is SECC.
2, ordinary cold rolled plate SPCC
SPCC is a steel ingot through the cold rolling mill continuously rolled into the required thickness of the steel coil or sheet.SPCC surface without any protection, exposed to the air is highly susceptible to oxidation, especially in the humid environment oxidation rate accelerated, the emergence of dark red rust, in use. The surface should be painted, plated or otherwise protected.
3, hot dip galvanized steel SGCC
Hot dip galvanized steel coil is a semi-finished product after hot rolling pickling or cold rolling, after cleaning, annealing, immersed in molten zinc tank at a temperature of about 460 ° C, and make the steel sheet plated with zinc, and then tempered and leveled and chemically processed into the SGCC material is harder than the SECC material, ductility is poor (to avoid the design of the deep pumping), the zinc layer is thicker, The zinc layer is thicker and the weldability is poor.
4, stainless steel SUS304
One of the most widely used stainless steel, because it contains Ni (nickel), so it is richer than the Cr (chromium) steel corrosion resistance, heat resistance, has very good mechanical properties, no heat treatment hardening phenomenon, no elasticity.
5, stainless steel SUS301
Cr (chromium) content is lower than SUS304, corrosion resistance is poor, but after cold processing in the stamping process to obtain good tensile strength and hardness, elasticity is better, and is used for shrapnel springs and anti-EMI.
Sheet metal processing is called sheet metal processing. Specific such as the use of sheet metal production chimneys, barrels, oil tanks, oil pots, ventilation pipes, elbows, elbows, sky, round, funnel-shaped, etc., the main process of shearing, bending, buckling, bending molding, welding, riveting, etc., requires a certain degree of geometric knowledge. Sheet metal parts is sheet metal parts, that is, can be stamping, bending, stretching and other means to process the parts, a general definition is the thickness of the parts in the process remains unchanged. Corresponding to the casting parts, forging parts, machining parts and so on.
