Stamping sheet metal processing technology commonly used material resolved

Author: ComeFrom: Date:2015/5/30 22:11:02 Hits:10208
    Stamping sheet metal processing technology commonly used material resolved as follows:
    Galvanized steel SECC
    SECC substrates for the average cold rolled coil, galvanized in a continuous production line after degreasing, pickling, electroplating and various post-treatment process, it becomes galvanized products. SECC not only has the mechanical properties of cold-rolled steel sheet and approximate general workability, and has excellent corrosion resistance and decorative appearance. Has a great competitive and substituting in the electronic products, home appliances and furniture market. Such as the current widespread use of computer chassis is SECC.
    Hot-dip galvanized steel SGCC
    Hot-dip galvanized steel coil refers to semi-finished products after the hot pickling or cold, after cleaning, annealing temperature of about 460 ° C immersed in molten zinc bath, leaving the steel coated with zinc layer, and then by quenching leveling and chemical treatment from. SGCC material harder than the material SECC, ductility (avoid deep drawing design), zinc layer is thicker, poor welding.
    Common cold rolled sheet SPCC
    SPCC cold rolled steel ingot means continuous rolling machine into the desired thickness of the steel sheet roll or sheet material. SPCC surface without any protection, exposure to easily oxidized in air, oxidation speed, especially in humid environments, appear dark red rust, in the use of the surface to be painted, plated or other protection.
    Stainless steel SUS304
    One of the most widely used stainless steel, because it contains Ni (nickel) so than containing Cr (chromium) steel richer corrosion resistance, heat resistance, have very good mechanical properties, non-hardening heat treatment, there is no flexibility.
