Strong magnet manufacturers tell why don't you suck stainless steel magnet?

The difference between the iron and steel in the carbon content. Carbon content is under two percent of the iron carbon alloy steel, carbon content over two percent is called iron. For stainless steel, regardless of the magnets on it or not, as long as meet quality standards, are stainless steel. Why don't we first, stainless steel rust? Its corrosion resistance are the main elements of chrome. Chromium content in more than eleven percent of the steel does not rust. Cr: a very hard metal in the world, the chromium plating on metal rust. Containing chromium, so is the stainless steel stainless steel. But chrome and stainless steel don't get sucked is no relationship. Second, why don't you get sucked stainless steel? Elements of nickel, nickel reserves in the world are very few, the price is expensive. Therefore, the high content of nickel in stainless steel in the market, the price also is higher, and the magnet is not on. This kind of steel we call austenitic steel. In fact, there is a stainless steel is not on the magnet. That is less high manganese containing nickel or nickel stainless steel. But this kind of steel will be a lot cheaper than austenitic steel. Remove the two kinds of stainless steel and other stainless steel were magnets. Because of austenitic stainless steel for low heat conductivity, using it to do the kettle, frying pan, pot is not appropriate, will be a waste of energy, has also extended boiling water to cook. Do with ferritic stainless steel frying pan, pot, not only has excellent corrosion resistance, and its thermal conductivity is higher than austenitic stainless steel nearly half. But this is sucked of stainless steel. So that we can conclude that the stainless steel is divided into a lot of kinds, but was only two magnets, one kind is used for decorative materials of austenitic stainless steel, the other is a high manganese content of stainless steel. Such as some other category of ferrite, martensite stainless steel are the magnets of absorption. For some stainless steel alloy elements, make stainless steel at room temperature and keep the face-centered cubic structure of gamma iron, so have no ferromagnetic. Under normal temperature, the stainless steel can be divided into austenite size according to the organization structure and martensite or iron grain size. Austenite size is non-magnetic or weak magnetic, martensite or iron grain size is a magnetic: ndfeb magnet application range have?
