304 stainless steel with or without magnetism?
Stainless steel friends are many, there are some differences in color, but not very good to distinguish. Can be judged according to the magnetic (magnet test): magnetic was 202 (ferritic stainless steel) magnetic or nonmagnetic small is 304 (stainless steel), are generally magnetic, but strength difference.
The magnetic material itself is not magnetic, because of some processing reasons, resulting in magnetic, but its relatively weak magnetic, and other carbon steel material is still different. 304, the magnetic properties of stainless steel is weak magnetic, if it is strong magnetic, it is not true 304 stainless steel.
This doesn't mean it is not qualified, because the most commonly used stainless steel decorative tube plate is Austenitic 304 material is generally non-magnetic or weakly magnetic, but fluctuations in chemical composition caused by smelting or processing of different magnetic properties may also appear, so it can not be considered to be counterfeit or substandard.
