Why is 304 stainless steel pipe magnetic when used
In life, we often use whether the tube is magnetic to judge the quality of stainless steel, but in fact, this method is very unscientific. For example, our common zinc tube alloy, tube copper alloy, etc. can generally imitate the appearance and color of stainless steel. And it is not magnetic, so it is easy to be mistaken for stainless steel.
