Use a magnet to attract to judge is not scientific

Stainless steel because of its beautiful appearance, corrosion resistance and no damage has become more and more popular. In the basin of boiler bowl gourd ladle, city sculpture, building and decorate room more and more used in stainless steel. However, people don't know much about the stainless steel. Some customers buy stainless steel kitchen utensils and appliances, and tried to get them fixed on the stainless steel container. Go together. Can think that the magnet is made of stainless steel suction, and stainless steel are not smoking. With general magnets attract good or bad is not scientific, suggesting that people still have misunderstanding on stainless steel. Usually, the difference is that the carbon content of steel. Carbon content is below 2% of the iron carbon alloy steel, carbon content is more than 2% of iron is called the iron. Steel due to its toughness, elasticity and rigidity is widely used. Steel exposed to life, but is different. For stainless steel, as long as meet the quality standard, stainless steel is stainless steel. Stainless steel corrosion resistance are the main elements of chrome. Chromium content is 10. 5% or more of the steel does not rust. When adding alloying elements is not at the same time during smelting, is to learn and be learned differences between magnets. Stainless steel are usually classified according to the organization's structure, and can be divided into austenite, ferrite and martensite, etc. If the different proportion of added to the molten steel, chromium nickel austenitic steel, stainless steel is a kind of can't be absorbed by magnet. If added chromium in the molten steel and a small amount of nickel ( And without nickel) The refined steel is magnet absorption of ferritic stainless steel. Chromium martensitic stainless steel is the main alloy elements, iron and carbon. Has more than 100 kinds of alloy stainless steel, its features and functions are different. Usually, austenitic stainless steel used for decoration, landscape and sculpture. Because of the low coefficient of thermal conductivity of austenitic stainless steel, so not suitable for use as kettle, POTS or rice cooker, it would waste energy and extend the boiling time. Back: on the principle of the magnets attract problem page: wonder why the magnet iron absorption occurs? 。 。
