【How to judge whether it is 304 stainless steel material?】
304 stainless steel is cold-worked and its structure will be transformation, the greater the degree of cold work deformation, the more transformation, the greater the magnetic properties of the steel.
On the contrary, the 256-series stainless steel of the second-class quality is likely to be nonmagnetic, so it is a mistake to judge that it is a genuine stainless steel.
In particular, the magnetic properties of 304 stainless steel due to the above reasons are not at the same level as the magnetic properties of stainless steel of other materials, which means that the magnetic properties of 304 steel always show weak magnetic properties.
This tells us that if the stainless steel strip is weakly magnetic or not magnetic at all, it should be judged as 304; if it is the same as the magnetic steel, it shows strong magnetism, because it is judged not to be 304 material.
