Shanxi Xin Stainless Steel wide to introduce you to: Project Standard JGJ 113-2003 "glass building application of technical regulations" JGJ 75-2003 "hot summer and warm in winter region residential building energy efficiency design standard" JGJ 134-2001 "hot summer and cold winter region residential building energy efficiency design standards "GB50352-2005" design of civil buildings "GB / T 50378-2006" Green Building Evaluation Standard "GB50096-1999 (2003 edition)" Residential Design Code "GB / T 50362-2005" housing performance assessment of technical standards "GB50189 2005 "public building energy efficiency design standard" JGJ 26 "Energy conservation design standard" GB50210-2001 "Building Decoration Engineering Quality Acceptance" Shanxi Guang Xin Stainless Steel introduce to you: the true and false identification of stainless steel products in the market to buy it Most of the material composition is not in line with the national standard stainless steel. The easiest way to identify the stainless steel is dissolved in 100ml of distilled water 8gCuSO4, then add 3 drops of concentrated sulfuric acid solution maintained 6min drop this on stainless steel products, stainless steel products will not really change the cell stainless steel rails, otherwise the steel surface depositing a layer of copper. Complex approach is for spectral analysis, if you have friends to do the job of professional stainless steel rails, that is a breeze. Stainless steel range is large, many types of stainless steel rails design, and some non-magnetic, and some with magnetic, mainly to see whether the steel containing iron, nickel, cobalt, if the magnetic tape, or non-magnetic. Such as stainless steel knife with magnetic, not some purely decorative materials with magnetic properties. In fact the degree of corrosion resistance of stainless steel is different, not absolute stainless steel. If you ask the main function is to prevent corrosion of stainless steel guardrail, 316L common good, but not a way to distinguish magnets suck. The best way is corrosion test, such as pH, salt spray test methods.
