How to distinguish the authenticity of stainless steel?

When using a magnet to attract a product, it means "stainless steel" if it is sucked, and "stainless iron" if it cannot be sucked. This method seems very scientific and popular. Actually, this method is not scientific! At present, among the five major types of stainless steels that have been developed and applied in the world, only austenitic stainless steels are basically non-magnetic (or weakly magnetic after processing), while ferritic stainless steels, duplex stainless steels, Martensitic stainless steel, and precipitation hardening stainless steels are all magnetic. Therefore, using a magnet to identify stainless steel often leads to incorrect judgment.

The correct identification method is to use stainless steel measuring solution for testing. At present, small bottles of stainless steel measuring solution are available in the market, with small volume, light weight, convenient portability, and low cost. By using the stainless steel measuring liquid method, we can easily identify some fraudulent behaviors and the true face of counterfeit stainless steel in the market to a certain extent.
