Katherine company specializing in the production of stainless steel hair crimped wire mesh. In stainless steel 316 and 317 stainless steel with aluminum, which in the marine environment and the chemical industry point of corrosion resistance substantially better than the 304 stainless steel. Among them, 316 stainless steel by a variety of low-carbon stainless steel 316L, 316N nitrogen and high strength stainless steel combined with higher sulfur content cutting stainless steel 316F. 321,347 and 348, respectively, titanium, niobium plus tantalum, niobium stabilized stainless steel crimped wire mesh, welded components suitable for use at high temperatures. 348 is one for the nuclear power industry, stainless steel, tantalum, and combined amount of drilling has certain limitations. How to identify the quality of stainless steel? Identification with copper sulfate will remove the oxide layer on the steel, put a drop of water, rub with copper sulfate, after wiping such as discoloration, usually stainless steel; such change purple, non-magnetic stainless steel for high manganese medical crimped wire mesh, There is generally an ordinary magnetic steel or low alloy steel. For the steel special properties, we need to take the following three approaches were identified. Identification Identification spent grinding mill is to spend on stainless steel grinder mill, watch his spark. A spark was streamlined, and there are many more dense flower festival, namely manganese high manganese steel or high manganese steel nitrogen; if there is no section shall spend chrome steel or chrome-nickel stainless steel. Identification of cold annealing chromium-nickel stainless steel, if the magnetic desirable piece of red-hot in the fire or into the water let the natural cooling (annealing) stainless steel crimped wire mesh pictures, in general, after magnetic annealing significantly reduced or completely disappeared. But some chrome-nickel stainless steel food stainless steel crimped wire mesh, such as steel and Cr21Ni5Ti Cr18Ni11Si4AlTi steel, Invar contains more ferrite elements, the internal organization of a considerable part of the ferrite. Thus, even in a state of thermal processing are also magnetic. Food stainless steel crimped wire mesh screen _ hair trillion (certified) _ stainless steel crimped wire mesh made by Anping Wire Mesh Products Co. trillion. Anping Wire Mesh Products Co. hair trillion (www.apfazhao.com) Hebei Hengshui, the wire mesh of the leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
