Metal Stamping Processing Commonly Used Materials Are What?

Jun 05, 2017

1, stainless steel SUS304, is one of the most widely used stainless steel, because containing Ni (NI) than CR (chromium) steel is more corrosion-resistant, heat resistance, has very good mechanical properties, no heat treatment hardening phenomenon, no elasticity.

2, stainless steel Sus301 (chromium) content is lower than SUS304, corrosion resistance is poor, but after cold processing can get very good tensile strength and hardness, better elasticity, used for shrapnel Springs and anti-EMI.

3, the ordinary cold-rolled plate SPCCISPCC is refers to the steel ingot passes through the cold rolling mill to make the request thickness the sheet metal roll material or the sheet material. SPCC surface without any protection, exposure to the air is extremely susceptible to oxidation, especially in the humid environment, the speed of oxidation, the emergence of dark red rust, in the use of the surface to paint, electroplating or other protection.

4, Galvanized steel sheet SECC substrate for the general cold rolled steel coil, in the continuous electroplating zinc production line after degreasing, pickling, electroplating and a variety of reprocessing process, that is, become galvanized zinc products. SECC not only has the mechanical properties and approximate processability of the general cold-rolled steel sheet, but also has superior corrosion resistance and decorative appearance. In the electronic products, home appliances and furniture market has a great deal of competition and substitution.

5, Hot Dip galvanized steel plate SGCC, hot dip galvanized steel coil refers to the hot-rolled pickling or cold-rolled semi-finished products, after cleaning, annealing, immersion temperature of about 460 °c in the dissolved zinc trough, and the steel sheet galvanized layer, and then through the leveling and chemical treatment. SGCC material than SECC material hard, ductile poor (avoid deep pumping design), zinc layer thicker, welding resistance is poor.
