Resolved stainless steel material

At present, the use of stainless steel determination liquid to identify stainless steel, in fact, only to a certain extent answered the question of "what is not", and can not really answer the question of "exactly what is". For example, using "Type 304" or "Ni8" testing liquid to test the so-called "304" products of the merchants, if the test results are the same as the real 304 products, we must not conclude that it is 304, but can only say that it is "probably" 304. Whether powered or not, the result of the test is only a necessary but not sufficient condition for determining that the steel under test is of a certain steel type (e.g. 304). If we really want to know the exact grade of steel, then it must be through professional chemical analysis or spectral analysis and other methods, comprehensive determination of its chemical composition.
In addition, the quality of stainless steel material is not only determined by its chemical composition, but also related to its organization, performance, purity and other factors. And for the determination of these factors, stainless steel determination liquid is obviously powerless, only with the help of professional testing.
