Metal stamping parts stamping processing material classification: 1. Ferrous metals: ordinary carbon structural steel, high-quality carbon steel, alloy structural steel, carbon tool steel, stainless steel, electrical silicon steel, etc. For rolled thin steel plates with a thickness of less than 4mm, according to the national standard GB/T708-1991, the thickness accuracy of the steel plate can be divided into A (advanced accuracy), B (higher accuracy), and C (ordinary accuracy). 2. Non-ferrous metals: copper and copper alloys, aluminum and aluminum alloys, magnesium alloys, titanium alloys, etc. 3. Non-metallic materials: cardboard, bakelite board, plastic board, fiberboard and mica, etc. 2. The commonly used stamping materials for the stamping of metal stamping parts are as follows: 1. Stainless steel SUS304 is one of the most widely used stainless steels. Because it contains Ni (nickel), it is more resistant to corrosion than steel containing Cr (chromium). Resistance, heat resistance, very good mechanical properties, no heat treatment hardening phenomenon, no elasticity. 2. Stainless steel SUS301, Cr (chromium) content is lower than SUS304, poor corrosion resistance, but cold processed metal stamping parts can obtain good tensile force and hardness, good elasticity, mostly used for shrapnel springs and anti-EMI. 3. Hot-dip galvanized steel sheet SGCC, hot-dip galvanized steel coil refers to the semi-finished product after hot-rolled pickling or cold-rolled, cleaned, annealed, and immersed in a molten zinc tank at a temperature of about 460°C to make the steel sheet It is coated with a zinc layer, then tempered, leveled and chemically treated. SGCC material is harder than SECC material, has poor ductility (avoid deep drawing design), thicker zinc layer, and poor electric weldability. 4. Galvanized steel sheet SECC, the substrate of SECC is general cold-rolled steel coil. After the continuous electro-galvanizing production line undergoes degreasing, pickling, electroplating and various post-treatment processes, it becomes an electro-galvanized product. SECC not only has the mechanical properties and similar processability of general cold-rolled steel sheet, but also has superior corrosion resistance and decorative appearance. It is highly competitive and replaceable in the market of electronic products, home appliances and furniture. 5. Ordinary cold-rolled plate 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, and it is easily oxidized when exposed to the air, especially in a humid environment, the oxidation speed is accelerated, and dark red rust appears. The surface should be painted, electroplated or other protections when in use.
