Hollow Long Round 316 38mm Stainless Steel Pipe 316L 60mm 80mm

  316 stainless steel pipe is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used to produce various conventional weapons, barrels, shells, etc.
   Internationally, the corrosion resistance of materials is divided into three categories according to the annual corrosion rate. The first category is complete corrosion resistance, and its corrosion rate is less than 0.1mm/year. High-quality stainless steel belongs to this type of material; the second category is corrosion resistance, which The corrosion rate is 0.1-1.0mm/year, which belongs to general stainless steel; the third category is non-corrosive, and its corrosion rate is greater than 1.0mm per year. The counterfeit stainless steel products discovered this time are analyzed and the corrosion rate is as high as 9.67mm/year, which is severely intolerant of corrosion. When further analyzing the composition of the product, it was found that the chromium content of the product, which represents an important indicator of stainless steel, was only 10.03% and 7.1%, which was far lower than the 10.5% minimum requirement of stainless steel for chromium.
