DT4A magnetic iron latest price

Pure iron is very soft metal, silver-white metallic luster, it can not make a sword, nor cast iron pot, plowshare. But pure iron after a certain amount of carbon, it becomes steel that we use in all aspects of the. Carbonaceous iron becomes more than 0.02 percent lower hardness can pull wire, rolling thin white iron and other low-carbon steel used. Steel in the range of 0.25 to 0.6% of the iron in the carbon content is called carbon steel, medium hardness, can be rolled into construction steel, steel, nails and other products. Iron carbon content from 0.6 to 2.0 percent when it became a high hardness can be prepared sword and die like a high-carbon steel. Low, medium and high carbon steels together called "carbon steel." If the iron content of more than 2.0% of carbon becomes hard and brittle cast iron pot can, radiators, pig iron a plow. Usually pig iron carbon content of 3.5% -5.5%. So the difference between pure iron, steel and cast iron main different is that the carbon content. Pure iron is a steel, its chemical composition is mainly iron content in 99.50% -99.90%, the carbon content of 0.04% or less, the other elements, the less the better. Because it is actually not a real pure iron, so called it A near-iron steel industrial iron. General industrial iron special soft texture, toughness particularly large, good electromagnetic properties. There are two common specifications, one is as deep drawing material may be stamped into a very complex shapes; the other is a magnetic material having a low sense of diamagnetic high magnetic widely used in electrical, electrical components, magnetic materials, amorphous articles, relays, sensors, automotive brakes, textile machinery, electric meter solenoid valve, etc. products. Higher than the melting point of iron in moist air difficult to rust than iron. Classification: according to use is divided into: magnetic iron, raw iron, no hairline iron, iron and other high vacuum tightness; divided according to mode of production: electrolytic iron, pure iron and wrought iron
