How to Identify Genuine 304 Stainless Steel Material

2016 09/08

Using 304 stainless steel measuring liquid, we can easily see through some of the fraud on the market and inferior 304 stainless steel tube true to some extent. For example, buy 304 grade 304 stainless steel, we can provide for manufacturers "304" products for testing. 304 is really the case, we used the above-mentioned '304 type "measurement liquid or" Ni8 "type assays were tested, it should be a corresponding test results, otherwise, it is not really 304; if then" low of Ni "determination was further tested purple beads drug discovery, it indicates that the product is a kind of high manganese steel, is also likely to be prevalent in the current market, the corrosion resistance of low and inferior 304 stainless steel, the so-called "200 series 304 stainless steel pipe" . When using 304 stainless steel tube measuring roughly Determination of specific elements about the test liquid identification, referencing and asked us to learn more about the national standard 304 stainless steel chemical composition requirements.


In addition, the quality 304 stainless steel tube material is not just the level of the chemical composition of its decisions, but also in its organization, performance, purity and other factors. For the determination of these factors, 304 stainless steel tube test liquid is obviously powerless, only by means of the relevant professional test test.

Currently on the market 304 stainless steel tube measuring liquid products, there is not enough scientific place in the logo. As mentioned above with "N" instead of "Ni" case, there will be 200 series 304 stainless steel tube is divided into "200,201,202" and so on. In actual use of the process also found that some test results is difficult to distinguish with the naked eye, prone to error. As the test in addition to the more obvious color difference between 201,202 and 301,304, but between 201 and 202, 301 and 304 between the color change is not very obvious. These unscientific and deficiencies of the manufacturers concerned need to be further improved.
