Detailed processing of five commonly used materials for Sheet metal processing

1. Stainless steel SUS301
The content of Cr (chromium) is lower than that of SUS304, and the corrosion resistance is poor. However, after cold working, it can obtain good tensile strength and hardness in the stamping process, and the elasticity is good, and it is mostly used for springs and EMI.
2. Hot dip galvanized steel plate SGCC
Hot-dip galvanized steel coil refers to the semi-finished product after pickling or cold rolling, which is washed, annealed, immersed in a molten zinc bath at a temperature of about 460 ° C, and the steel sheet is plated with zinc layer and then tempered. Leveling and chemical treatment. SGCC materials are harder and less ductile than SECC materials (avoid deep draw design), thicker zinc layers, and poor weldability.
Three. Stainless steel SUS304
One of the most widely used stainless steels, because it contains Ni (nickel), is more resistant to corrosion and heat than steel containing Cr (chromium). It has very good mechanical properties, no heat treatment and hardening, and no elasticity.
4. Suzhou Sheet metal processing ordinary cold rolled sheet SPCC
SPCC refers to the continuous rolling of steel ingots into coils or sheets of the required thickness through a cold rolling mill. The SPCC surface does not have any protection. It is easily oxidized when exposed to air, especially in humid environments. It has a dark red rust and should be painted, plated or otherwise protected during use.
V. Suzhou Sheet metal processing galvanized steel sheet SECC

SECC's substrate is a general cold-rolled steel coil, which becomes an electro-galvanized product after the continuous electro-galvanizing line undergoes degreasing, pickling, electroplating and various post-treatment processes. 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. It has great competitiveness and substitution in the market of electronic products, home appliances and furniture. For example, the SECC is commonly used in computer cases.
