Nickel element in world reserves of rare, expensive. Thus, long magnets with high nickel content stainless steel in the market price is higher, but not on the magnet also suck. In fact, there is a stainless steel magnet is not sucked on. That is less high manganese nickel or nickel-free stainless steel. This stainless steel market price higher than the nickel-containing stainless steel lower than 1000 yuan per ton. Some dealers are taking advantage of people "good stainless steel magnet are not sucked up" misunderstandings, long magnet manufacturers, consumer fraud, price and high-nickel stainless steel as expensive. There are 100 kinds of stainless steel, features and functions are not the same. General decoration, landscape, sculpture selection of austenitic stainless steel. Because the low thermal conductivity of austenitic stainless steel, with it kettle, frying pan, rice cooker is inappropriate, it would be a waste of energy, but also extend boil water for cooking time. Ferritic stainless steel do wok, rice cooker, not only has excellent corrosion resistance, and its thermal conductivity higher than that of austenitic stainless steel by nearly half. Washing machine drum, food, vegetables basin, as long as contact with water containers must be selected ferritic stainless steel. Some people complain of stainless steel knives fast, long a magnet phone manufacturers, it is because the wrong choice of stainless steel. Austenitic stainless steel can not be hardened, not suitable for cutting tools, cutting tools. Martensitic stainless steel knives made by heat treatment, such as quenching, tempering steel hardness change. The magnet produces a magnetic field, this magnetic field through the surrounding people and objects. Namely the existence of something. You can call it radiation. Ordinary magnetic field on the sound, even without the magnet, the Earth itself has a magnetic field, and you have nowhere to escape. If you really to no magnetic fields, maybe people will not meet, long magnet wholesale supply, at least some of the animal's survival is required magnetic field. Scientific answer is that there is radiation, but no radiation damage. All objects will be issued with a temperature of electromagnetic radiation, this concept is called "blackbody radiation", high school physics might involve a little relevant content. Any natural substance which, inevitably contain a bit of radioactive material, there will be some radioactive emissions, but a normal magnet should not be able to harm the human body radiation intensity.
