Austenitic Stainless Steel Identification

Stainless steel plate is not a product of corrosion, it was said that the identification of stainless steel plate is very simple, with a magnet! It is the stainless steel plate that can't be sucked, and the stainless iron plate can suck it. At present, this statement and practice seem to be very fashionable. It is unscientific and erroneous for such statements and practices to be denied by relevant persons.

    Of the five major stainless steels currently developed and applied in the world, only austenitic stainless steels are often non-magnetic while ferritic stainless steel plates, duplex stainless steels, martensitic stainless steels, and precipitation hardened stainless steels are all magnetic.

Regardless of magnetic properties, each stainless steel has its own characteristics and applicable range. For austenitic stainless steel plates that cannot be inhaled with magnets, the use of manganese and nickel-nitrogen reduces the cost and strength of the steel compared to the corresponding steel.

However, because of its reduced corrosion resistance, its application fields are narrow, and those fields that require high strength, non-magnetic, and low corrosion resistance, such as springs and electronic devices, are often used. In terms of corrosion resistance, these products cannot even be called stainless steel, nor can they be called stainless steel at all.

    In the current market, some of the so-called stainless steel is the larger problem steel, counterfeit steel, but it is just like austenitic stainless steel, it is precisely the non-magnetic austenitic steel! It can be said that the use of magnets in the current market to identify the advantages and disadvantages of stainless steel, often connivance counterfeit stainless steel.

Excluding high-quality magnetic ferrite and other steel species, but also due to cost factors squeeze out the non-magnetic austenitic stainless steel, and may even make this counterfeit steel to be used as non-magnetic austenitic stainless steel and used in Industrially. Therefore, it is obviously not feasible to identify the true and false qualities of stainless steel plates by using the method of using magnets, and it should be determined by practical methods....
