Stainless steel water pipes, with a very low leakage rate, can save valuable water resources characteristics, now gradually replacing the old-style water pipes, in daily life, how to distinguish whether the water pipe material is 201 or 304?
The most commonly used is to drop stainless steel testing solution on the surface of stainless steel, the principle is to cause a chemical reaction between the elements contained in the material and the substance in the identification potion to produce a colored substance, to see the color change in the potion to determine whether the material is 304 or 201.
Another method is to use a spectrometer. Spectrometer measures the light reflected from the surface of an object, and by capturing and analyzing the light information through the spectrometer, it can measure which elements are contained in the object. .The use of stainless steel can be instantly detected when the content of various types of elements, you can determine the material is 304 or 201, fast and reliable.
