Promote the industrial development of stainless steel wire stainless steel wire as extended processing of metal wire products business units with steel strip steel division, the Institute had conducted a series of close and fruitful co-development and research topics, research and development in technology continue to accumulate experience , but also continue to achieve breakthroughs in operational synergies. Today, with the Joint Research Centre of the newly established platform stainless steel wire, three units will integrate their superior resources of common interest to expand the products and technologies focused research to address key technical issues of new products and the use of wire 316 stainless steel wire, This is also a useful attempt internal group collaboration downstream operations. The establishment of the research center will further develop and strengthen the system benefits and then from stainless steel wire rod products, raw materials to and accelerate the transformation of scientific and technological achievements, promote world-class products, wire and bases. How to identify the stainless steel wire rope (two), but high carbon steel type 420 and 440 points during nitric acid test is slightly corroded, non-ferrous metals encountered in concentrated nitric acid corrosion immediately, and dilute nitric acid has a strong corrosive to carbon steel. The easiest way to spot test method copper sulfate copper sulfate point test is quick to distinguish ordinary carbon steel, and all types of stainless steel wire rope, the concentration of copper sulfate solution used is 5% -10%, before making point test, the test area should be thoroughly remove oil or other contaminants 304L stainless steel wire, and with sanding or polishing cloth Polishing a small area, and then try to polish droplets at ordinary carbon steel or iron in a few seconds, it will form a surface of the metallic copper, and the surface of the stainless steel test point copper precipitation is not generated or display color of copper. Sulfuric acid immersion test method can 302 and 304 stainless steel with 316 and 317 to distinguish. Trimming the sample to be finely ground, and then in a volume concentration of 20% to 30%, temperature 60 ~ 66 ℃ sulfuric acid cleaning and passivation of half an hour, the volume concentration of 10% sulfuric acid solution was heated to 71 ℃ When well-known brand of stainless steel wire, 302 and 304 immersion solution was rapidly corrode steel and produce large amounts of air bubbles in the sample black within minutes; and 316 and 317 samples of the steel from corrosion or erosion is very slow (not bubbles), the test within 10 to 15 minutes does not change color. If the test sample simultaneously with a known composition to approximate comparison, the test can be more accurate.
