How to distinguish between 201 stainless steel and 304 stainless steel?
Yes, there are many ways to identify 201 stainless steel and 304 stainless steel. Usually factory procurement will be identified by chemical agents, but this method is not suitable for ordinary consumers. Some people say that the sound made by tapping the cup is used for identification, but this method is unscientific and incorrect.
Dongguan Zhan Yi Commodity Technology Co.,Ltd. will now teach you a particularly simple and effective method.
Since 201 stainless steel has obvious magnetism, but 304 stainless steel does not, you can find a small magnet. The one with obvious suction force must be 201 stainless steel, otherwise it is 304 stainless steel.
This is the inspection method with the aid of tools, and the other is to look at the polished surface of the water cup or the welding line. If you find that the cup is black or has a rust-like condition, it is 201 stainless steel. If not, it may be 304 stainless steel. Why is it possible?Because 201 stainless steel will rust may be caused by the market or special circumstances, not all welding lines will be black and rusty.
