Some misunderstandings of stainless steel material identification
1, the magnet on the sucker must not be stainless steel.
This is the biggest misunderstanding in the hearts of the Chinese people! It can be said that if you go to any hardware vendor, the boss will tell you so. If you believe, then you are actually wrong. Magnets do not necessarily absorb stainless steel. (Note that there are three nonsense words in this sentence.) Stainless steel can be divided into many types. Among them, the commonly used methods include austenite, ferrite, two-phase, martensite, precipitation hardening, etc. (Do not ask me these terms.) What do you mean, remember on the list, these are metallurgical terms.) Of these, only austenitic stainless steels are non-magnetic, but these stainless steels account for most of the stainless steel market (previously more than 70%, and now only an estimated 60%, to the next 50%), the most widely used. The other iron and steel materials are magnetic, which is the reason that the Chinese domestic market uses magnetic discrimination stainless steel. However, other types of stainless steel are magnetic. For example, many times you try high-end restaurants using magnets to try shiny stainless steel knives and forks. They are often magnetic. In fact, it is likely to be martensitic stainless steel. There are also auto exhaust pipes. Stainless steel is also magnetic. It is ferritic.
Austenitic stainless steels are often added with Ni. At present, the price of Ni is high in the world. Therefore, the main trend of stainless steel is how to save nickel. One of the best ways is to develop excellent ferritic stainless steel and two phases. Therefore, in the future, there will inevitably be more stainless steel that can absorb magnets.
