Kunshan Xuanrun Precision Machinery Co., Ltd. specializes in producing sheet metal parts with high quality, long service life, and stable performance. Such good sheet metal parts cannot be separated from good sheet metal materials. So what are the commonly used sheet metal materials? There are many sheet metal materials suitable for stamping processing, and there are also many sheet metal materials widely used in the electronic and electrical industry. Below, we will introduce them to you.
1. Ordinary cold-rolled plate SPCC: SPCC refers to steel ingots that are continuously rolled into steel coils or sheets of the required thickness by a cold rolling mill. The surface of SPCC has no protection and is highly susceptible to oxidation when exposed to air, especially in humid environments where the oxidation rate accelerates and dark red rust appears. When in use, the surface should be painted, electroplated, or otherwise protected.
2. Galvanized steel plate SECC: SECC's substrate is a general cold-rolled steel coil, which becomes an electroplated product after undergoing degreasing, acid washing, electroplating, and various post-treatment processes in a continuous electroplating production line. SECC not only has the mechanical properties and approximate processability of general cold-rolled steel sheets, but also has superior corrosion resistance and decorative appearance. There is great competition and substitutability in the markets of electronic products, home appliances, and furniture. For example, SECC is commonly used in computer cases at present
3. Hot dip galvanized steel plate SGCC: Hot dip galvanized steel coil refers to a semi-finished product that has been hot-rolled, pickled, or cold-rolled, cleaned, annealed, and immersed in a molten zinc bath at a temperature of about 460 ° C to coat the steel sheet with a zinc layer, and then quenched, tempered, leveled, and chemically treated. SGCC material is harder, less ductile (avoiding deep drawing design), has a thicker zinc layer, and has poor weldability compared to SECC material
4. Stainless steel SUS301: The content of Cr (chromium) is lower than SUS304, and its corrosion resistance is poor. However, after cold processing, it can obtain good tensile strength and hardness, and has good elasticity. It is mostly used for spring plates and anti EMI
5. Stainless steel SUS304: One of the most widely used stainless steels, it has better corrosion resistance and heat resistance than steel containing Cr (chromium) due to its Ni (nickel) content. It has excellent mechanical properties, no heat treatment hardening phenomenon, and no elasticity.
