In the conventional primary colors stainless, austenitic stainless steel is the most suitable coloring material can be obtained a satisfactory color appearance. Ferritic stainless steel due in the coloring solution increases the likelihood of corrosion resulting bright color than the former. The low chromium and carbon martensitic stainless steel, because of its corrosion resistance is even worse, you can only get dark color or black surfaces. According to reports, the austenitic stainless steel by using low-temperature surface oxidation coloring colored, exposed to the industrial atmosphere for six years, exposed to the marine atmosphere a year and a half, soaked in boiling water for 28 days, or heated to about 300 ℃ , it did not change its color gloss. In addition, it can withstand normal molding processing, drawing and bending and machining sclerosis. WiQ industrial design. China currently, colored stainless steel except for the outer walls of buildings and window frames decorated, it can also be used in many other areas. For example, a black stainless steel plate solar collector panel that selects the heat absorption rate up to 91% to 93%. In the arts and crafts field, stainless steel and color printing combined with polishing and etching may be cooperating outlets law process to produce three-dimensional relief murals never fade, hanging like. In addition, color stainless steel appliances, cookware, kitchen equipment, bathroom appliances, the favorite of consumers. Pull plate (LH), also called hairline, because the lines as thin and straight hair. Its surface like filamentous texture, which is a process of stainless steel. Matt surface is carefully to see if the slightest trace of texture above, but do not touch it, wear-resistant than stainless steel is generally bright side, look on the grade number. Hairline board has a variety of lines, there are Hairline (HL), snow sand grain (NO4), and a groove (random pattern), cross pattern, cross lines, etc., all the lines are cast by oil hairline machine according to the requirements process and into, then plating coloring.
