316 Stainless Steel Tube Of Genuine Recognition

316 stainless steel tube of genuine recognition

316 Stainless Steel Pipe is a hollow long round steel, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical, instrumentation and other industrial pipeline and mechanical structure parts. In addition, bending, torsional strength, light weight, so it is widely used in the manufacture of mechanical parts and engineering structures. Also commonly used for the production of conventional weapons, the barrel shells.

For now, the international annual corrosion rate of the corrosion resistance of the material is divided into three categories, completely corrosion, the corrosion rate of less than 0.1mm / quality stainless steel pipe belonging to such material; second The category is yet corrosion, the corrosion rate of 0.1-1.0mm / year, a general Stainless Steel Pipe; third category is not corrosion, the corrosion rate is greater than 1.0mm per year. The discovery of counterfeit Stainless Steel Tube products through analysis of the corrosion rate of up to 9.67mm / year, is a serious corrosion. In further analysis of the composition of the product, the product on behalf of the Stainless Steel Pipe an important indicator of chromium content of 10.03% and 7.1%, well below the 10.5% of the requirements of the minimum requirement of stainless steel chrome. In general, the chromium content greater than 10.5% of the iron-based alloys known as stainless steel, while the two products of its chromium content is far below the lower limit, the product is simply not the stainless steel. The reason for the market of the product, the producer by greed, the people on the stainless steel understanding the vulnerability of the fraud. It is generally believed that the Stainless Steel Pipe with magnetic counterfeiters through the extensive use of manganese-generation nickel practices, change the product ingredients, has been both a magnetic and extremely low cost materials, and to reap high profits. The appearance of the product circulating in the market, usually Stainless Steel Tube is difficult to distinguish, at the same time, not magnetic, coupled with unscrupulous dealers to take trick-doped mixed sell, cause great difficulty to the consumer to identify the authenticity, the use of may result in unforeseen consequences. In addition this material in a small amount of nickel, but can not play nickel its due role, is a waste of precious metals, resulting in a waste of resources.
