But at a high temperature impact properties were significantly decreased under tensile strength and low temperatures.Corrosion of metal plate production processCorrosion of metal plate production processCorrode metal plate is also called etching plate. The main search using the mask, after etching process processing system to do three steps from the Braille metal plate or a concave metal plate.Corrosion of metal plate production process:1) Cutting: by drawing (layout size) in size, surrounded by more than plus not less than 5mm burrs.
