Science 丨 'Misunderstanding' of 304 stainless steel pipe 2020-08-12 When we first contact 304 stainless steel pipe, there will be some misunderstandings. Although we have also learned about it, it is found in statistics that some people are relatively simple about 304 stainless steel pipe. There are some misunderstandings in the problem, so that the editor has to 'cleanse' stainless steel pipe 304! 304 stainless steel pipe manufacturer 304 stainless steel pipe misunderstanding 1304 stainless steel pipe will not 'rust' people often think that 'stainless steel' means 'no growth' 'Rusted steelThis understanding is of course too simple. First of all, the 'stainlessness' of 304 stainless steel pipe is not that it does not rust, but that it does not rust under certain conditions. If the user uses it improperly and uses it in an environment or condition that exceeds its corrosion resistance, it will naturally rust. For example, chloride ions are widespread, such as salt, sweat, sea water, sea breeze, soil and so on. Secondly, 304 stainless steel pipe should not be in contact with iron for a long time. Different metal ions will reduce the corrosion resistance of stainless steel. Misunderstanding 2 Is it good stainless steel without magnetism? Many customers go to the market to buy 304 stainless steel pipes with a small magnet. Without magnetism, there will be no rust. In fact, this is a misunderstanding. The non-magnetic stainless steel pipe 304 is determined by the organizational structure. The so-called 200 series and 300 series stainless steel pipes with high manganese content and low nickel content currently circulating in the market are not magnetic, but their performance is very different from that of 304 with high nickel content. On the contrary, 304 will be slightly magnetic after stretching, annealing, polishing, casting and other processes. Therefore, it is a misunderstanding and unscientific to judge the quality of stainless steel pipes without magnetism. 304 stainless steel pipe manufacturer 304 stainless steel pipe product map The simple way to identify the true and false of 304 stainless steel pipe is as follows: 1. The color and smoothness of the steel surface distinguish the true and false of the steel. 2. The price is extremely low, and there is a high possibility that it is fake. 3. See if there is a 304 stamp on the steel body of the stainless steel pipe. 4. Use stainless steel to detect the potion. It is true that 304 stainless steel will not turn red.
