What are the commonly used processing materials for precision stamping parts? [Hardware]

The processing and forming of precision stamping parts require processing materials, and the quality and performance of stamping parts are different for different materials. Stamping materials are an important factor affecting the quality of stamping parts and die life. So what are the commonly used processing materials for precision stamping parts? The commonly used stamping materials for precision stamping parts are as follows: 1. Stainless steel SUS304 is one of the most widely used stainless steels. It contains Ni (nickel) than Cr ( Chromium) steel is rich in corrosion resistance, heat resistance, has very good mechanical properties, no heat treatment hardening phenomenon, no elasticity. 2. Stainless steel SUS301 has a lower Cr (chromium) content than SUS304, and has poor corrosion resistance, but it can obtain good tensile force and hardness after cold working, and has good elasticity. It is mostly used for shrapnel springs and EMI prevention. 3. 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. 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. Hot-dip galvanized steel sheet SGCC, hot-dip galvanized steel coil refers to the semi-finished product after hot-rolled pickling or cold-rolling, washed, 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.
