Stainless steel construction engineering _ _ Fu-together

 Stainless steel products not only gives the coloring of various colors stainless steel engineering processes, increase the variety of products, and improve product wear and corrosion resistance. There are several methods colored stainless steel: ⑴ chemical oxidation coloring: that in a specific solution, the color of the film is formed by chemical oxidation with dichromate method, mixed sodium method, curing method, the acidic and alkaline peroxide oxidation method. Generally, "Yin Branch Law" more (INCO) use, but a number of products in order to ensure consistent color, it must be controlled by the reference electrode. ⑵ electrochemical coloring: in particular solution, the color of the film formed by electrochemical oxidation. ⑶ ion deposition oxide coloring chemical method: stainless steel workpiece is placed in a vacuum coating machine for vacuum evaporation plating. For example: titanium gold watch case, watch band, usually gold. This method is suitable for high-volume processing. Because investment, high-quality stainless steel project cost, low-volume products uneconomical. ⑷ temperature oxidation coloring: molten salt in particular, showing a variety of different colors to keep the workpiece is immersed in a certain process parameters, so that the workpiece to form a certain thickness of the oxide film, and. ⑸ vapor cracking coloring: Shandong quality stainless steel process is more complex, rarely used in industry. In the case of containing a lower C, Cr content of 18% to 28% stainless steel works, Ni content of 3% to 10%. Some steel further contains Mo, Cu, Si, Nb, Ti, N and other alloying elements. Both austenitic class steel and ferritic stainless steel features, higher compared with ferrite, ductility, toughness, brittle at room temperature, resistance to intergranular corrosion and welding performance are significantly improved, while maintaining iron ferritic stainless steel 475 ℃ brittle and high thermal conductivity, with superplastic characteristics.
