Iron and steel are different in terms of carbon content
Stainless steel is usually divided according to the structure of the organization, can be divided into austenite, ferrite, martensite and other major categories. If you go into the molten steel of different proportion of Cr Ni austenitic steel, tempered magnet is not stainless steel; if the chromium nickel steel and a small amount to in (or without nickel), tempered steel is a magnet on the stainless steel, also called ferritic stainless steel; martensitic stainless steel alloy the element is chromium, iron and carbon. Stainless steel because of the different alloy content, there are more than 100 kinds. In addition to the austenitic stainless steel magnet not on ferrite and martensitic stainless steel are magnetic. Nickel is scarce in the world and expensive. Therefore, the high nickel content of stainless steel in the market price is higher, but the magnet still can not suck. In fact, there is also a stainless steel magnet can not be sucked.
That is, high manganese content, less nickel or nickel free stainless steel. This stainless steel market costs more than 1000 yuan per ton of stainless steel with nickel. Some dealers is the use of good people are not on the stainless steel magnet suction misunderstanding, to deceive consumers, so the price as high with expensive stainless steel.There are more than 100 kinds of stainless steel, and the characteristics and functions are different. General decoration, landscape, sculpture using austenitic stainless steel. Because of the low thermal conductivity of austenitic stainless steel, using it as a kettle, wok, rice cooker is not appropriate, will use a lot of energy, but also to extend the boiling water cooking time. Using ferritic stainless steel as a wok and rice cooker, not only has excellent corrosion resistance, but also its thermal conductivity is nearly half higher than that of austenitic stainless steel.
. An iron carbon alloy with a carbon content of less than 2% is a steel, and a carbon content of more than 2% is called iron. Steel is widely used because of its toughness, elasticity and rigidity. Life is exposed to steel, but people call different. For stainless steel, whether or not the magnet is sucked on or not, as long as the quality standards are met, it is stainless steel. Therefore, from the perspective of metallurgy said, no rust said. The main element of stainless steel corrosion resistance is chromium. If the content of chromium is above 10.5%, the steel will not rust. When smelting, the alloy elements added are different, so there is a difference between the magnet and the suction.
