A lot of people buy stainless steel product to the market, oneself takes a small magnet, when seeing money, suck, thinking not to suck those who go up is good stainless steel. Did not take magnetism to won't rust, actually this is a kind of wrong understanding. Stainless steel belt does not take magnetism organize structural decision, because caky temperature can be not formed together,molten steel is in among caky process " ferrite " . "Austenite " , " martensite " the stainless steel that waits for different organization structure, among them " ferrite " , " martensite " stainless steel takes magnetism. And " austenite " join forces of its put together learns stainless steel function, technical properties solderability is good, but only of from corrosion resistance character belt magnetism " ferrite " stainless steel is ambitious at " austenite " stainless steel.
What the Gao Han manganese with at present current market contains nickel less is alleged stainless steel of 200 series, 300 series also does not take magnetism, but of its function and Gao Han nickel of 304 far apart, instead, 304 courses drawing, anneal, polish, cast wait for craft processing to also be met microstrip is magnetic, because this uses stainless steel belt not to take magnetism to judge the actor of low quality of stainless steel,be a kind of misunderstanding, also be unscientific.
