The stainless steel plates produced by Tisco and Outokumpu are compared in terms of chemical composition and mechanical properties. The main factors affecting the quality of the plates are chemical elements such as chromium (Cr), molybdenum (Mo) and nickel (NI). ) The percentage of the cathode plate material we have ordered is relatively high. The content of these main elements, chromium molybdenum and nickel, and the mechanical properties of the plate are improved, which can effectively solve the corrosion and deformation of the current plate.
