Electrically welded thick steel sheets with a hot dipped or phosphate treated layer on the surface SGCC hot dipped galvanized iron coil means hot tied pickled passivated or hot rolled, cleaned, quenched and then semi-finished processed. (quenched), immersed at an ambient temperature of roughly 460°C. In a molten zinc bath at 460°C, the hot-dip galvanised layer on the steel is subsequently quenched, levelled and finished with a chemical solution (CH3l1). SGCC raw material (material) is harder and more solid than SECC raw material, with poor plasticity (to prevent deep drawing design solutions), a thick zinc layer and poor malleability for small sheet metal processing.
Stainless steel (stainless steel acid-resistant steel) SUS301 (permanent jump) Cr (chromium) accounted for less than SUS304, and weaker corrosion resistance, but after cold-drawing can achieve better tensile strength and strength, and has a good ductility. It is suitable for spring sheet torsion springs and anti-EMI. sheet metal painted sheet metal has the characteristics of light weight, high compressive strength, good electrical conductivity (can be used for magnetic shielding), low cost, and good mass production characteristics. It has been widely used in electronic products, communications, automotive industry, medical equipment and other industries, for example in electronic computer cases, mobile phones and MP3, sheet metal is an indispensable component. The processing of automotive chassis in Suzhou is the core technology that sheet metal professionals must be skilled in, and the sheet metal processing plant is the main whole process of producing sheet metal goods. It does not only contain the traditional laser cutting and falling, stamping processing, bending and forming methods and the main parameters of the process, but also the structural characteristics and the main parameters of the process of various cold stamping dies, the basic principles and operating steps of various facilities, and its new stamping processing technicality and new processes.
Stainless steel (acid-resistant stainless steel) SUS304 is one of the most commonly used stainless steels (acid-resistant stainless steel). Because it includes nickel (Ni), it is more resistant to corrosion and temperature than steels containing magnesium (Cr). Excellent physical properties, no heat treatment process (chǔlǐ) hard bottoming, no elasticity.
