welding thick steel plate SGCC hot-dip galvanized iron coil with hot-dip or phosphating layer on the surface refers to the processing of semi-finished products after hot-pickling passivation or hot-rolling, cleaning and quenching. (Quenching), immersion is carried out at an ambient temperature of approximately 460°C. In a molten zinc bath at 460°C, the steel is hot-dip galvanized, followed by quenching, leveling and chemical settlement (CH3l1). SGCC raw materials (materials) are harder than SECC raw materials, have poor plasticity (to prevent deep drawing design), thick zinc layer, and poor malleability in small sheet metal processing.
stainless steel (stainless steel acid-resistant steel) SUS301 (permanent jump) Cr (chromium) accounts for less than SUS304, and its corrosion resistance is weak, but it can obtain better tensile strength and strength after cold drawing, and has better ductility. It is suitable for leaf springs, torsion springs, and EMI suppression. Sheet metal paint sheet metal with light weight, high compressive strength, good conductivity (can be used for magnetic shielding), low cost, good mass production characteristics. It has been widely used in electronic products, communications, automotive industry, medical equipment and other industries, such as electronic computer chassis, mobile phones and MP3, sheet metal is an indispensable part. Suzhou automobile chassis production and processing is the core technology that sheet metal professionals must master, and the sheet metal processing plant is also the main process of producing sheet metal products. It not only contains the traditional laser cutting and blanking, stamping processing, bending and forming methods and process parameters, but also contains the structural characteristics and process parameters of various cold stamping dies, the basic principles and operation steps of various facilities, and its new stamping technology and new technology.
Stainless steel (acid-resistant stainless steel) SUS304 is one of the most widely used stainless steels (acid-resistant stainless steel). Because it includes nickel (nickel), it has more corrosion resistance and temperature resistance than steel containing magnesium (chromium). Excellent physical properties, no heat treatment process (ch ǐ l ǐ) hard bottom, inelastic.
