Why is stainless steel magnetic? 

Most stainless steel products are non-magnetic, but some stainless steel products will generate working magnetism during the production process, such as stainless steel wire rope, all non-magnetic to judge stainless steel is unscientific. Because of the fluctuation of chemical composition during the smelting process, it may appear magnetic, but this cannot be considered as an unqualified product. In addition, when stainless steel is cold-worked, the microstructure will also be transformed into Martens, and the more the transformation, the greater the magnetic properties. Conversely, 200-series stainless steel, which is of lower quality, is likely to be non-magnetic. 

How to identify genuine and fake stainless steel products?

  1. Test with stainless steel test potion.

  2. Chemical composition analysis with spectrometer

  3. Salt spray test to simulate the actual use environment

What are the commonly used stainless steels? What is the usage environment? 

1. 201 stainless steel, suitable for use in indoor environments

2. 304 stainless steel for use in outdoor environments
