What are the sheet metal parts suitable for stamping?

2019-01-08 07:19:51

There are a lot of sheet metal materials suitable for stamping, which are widely used in electronic and electrical industry, including:
1. Common cold rolled plate SPCC
SPCC refers to the steel ingot after the cold mill continuous rolling into the required thickness of steel sheet coil or sheet. SPCC surface does not have any protection, it is easy to be oxidized when exposed to air, especially in the humid environment, the oxidation speed is accelerated, dark red rust appears, the surface should be painted, electroplated or other protection.
2. SECC of galvanized steel sheet
SECC's base material is ordinary cold-rolled steel coils, which become electrogalvanizing products after degreasing, pickling, electroplating and various post-treatment processes in the continuous electrogalvanizing production line. SECC not only has the mechanical properties and similar machinability of general cold-rolled steel sheet, but also has excellent corrosion resistance and decorative appearance. In the electronic products, household appliances and furniture market has great competitiveness and substitution. For example, computer case is commonly used SECC.
3. Hot dip galvanized steel SGCC
Hot dip galvanized steel coil is hot rolled after pickling and cold rolling of semi-finished products, after cleaning, annealing, immersion temperature of about 460 ° C in zinc melt trough, and make the sheet steel on zinc plating layer, then through conditioning leveling and chemical treatment. SGCC materials are harder than SECC materials, with poor ductility (avoid deep drawing design), thicker zinc layer and poor weldability.
4. Stainless steel SUS301
Cr (Cr) content is lower than SUS304, corrosion resistance is poor, but after cold processing can get good tension and hardness, good elasticity, mostly used for spring and anti-emi.
5. Stainless steel SUS304
One of the most widely used stainless steels, because containing Ni (nickel) than Cr (chromium) containing steel is rich in corrosion resistance, heat resistance, has very good mechanical properties, no heat treatment hardening phenomenon, no elasticity.
