Some friends in the purchase of stainless steel slide rail, will use a magnet to attract a suction, think that stainless steel material, by the magnet adsorption is false, not by the magnet adsorption is true, in fact, this is a very wrong judgment. Generally speaking, stainless steel is magnetic and non-magnetic, austenitic stainless steel is weakly magnetic or non-magnetic, such as 201,304, martensite or ferrite is magnetic, 430,310, etc. Due to improper heat treatment during smelting, there is a small amount of martensite or ferrite in austenitic stainless steel, so there will be micro-magnetism in stainless steel. The small accessories inside the slide rail produced by the general slide rail hardware company are made of stainless steel, and the manufacturer has not done demagnetization treatment, so there will also be the phenomenon that magnets can be adsorbed. It is not widely circulated that stainless steel can be adsorbed is fake, but cannot be adsorbed is real.
