Many people generally think that the brighter the surface of the 304 stainless steel belt, the better its quality and the higher the purity. In fact, this is a misunderstanding of understanding, and the purity of the material has no obvious relationship with the brightness.
At present, there are many technologies that can change the brightness of the stainless steel surface, and the current polishing technology is very good, but polishing does not mean that the composition of the stainless steel will change.
In the production process of stainless steel, a lot of different other metals will be added to finally become 304 stainless steel material, so what are the standards to judge the quality of stainless steel strips?
In fact, the purity of the stainless steel strip does not indicate the quality of the stainless steel strip, but is judged by the content of various components in the production process.
For example, if the proportion of chromium contained in the stainless steel strip is high, the strength, wear resistance and toughness of the stainless steel strip will be relatively strong. If the proportion of nickel content in the stainless steel strip increases, the anti-rust ability of the product will be stronger. Therefore, if you want to go to the quality of stainless steel, you need to look at the ingredients it contains.
At present, there are two kinds of surface raw materials for 304 stainless steel strips we see on the market, one is BA and the other is 2B. Because this kind of stainless steel belt is the most widely used, plus itself is good, low price, strong machinability, etc., it is favored by users, but users can not only judge it by the brightness and purity of the surface when choosing and buying the quality of.
