What's the difference between pig iron and nickel iron?
Pig iron is an alloy of iron and carbon carbon content more than 2%, pig iron carbon content is generally in 2.11%--4.3%, including C, Si, and Mn, S, P and other elements, is the use of iron ores in blast furnace smelting products. According to the different form of carbon in pig iron, it can be divided into several kinds, such as steelmaking pig iron, casting pig iron and nodular cast iron. Pig iron performance is hard, wear-resistant and casting good, but pig iron is crisp, can not forge.
An iron carbon alloy with a high carbon content; a low carbon steel containing nickel iron. Their performance is very different, nickel iron should belong to alloy steel.
As the nickel iron alloy element additive in steelmaking industry, steel can improve the bending strength and hardness of cast iron in the uniform structure, density increased, can also be used as a nickel or nickel containing cast iron roll and other casting alloy addition agent.
Nickel iron and pig iron are two different things, not a class of products, without contrast or distinction. The two products are different in production purpose. Smelting nickel iron out of the nickel iron alloy, pig iron contains more metal elements, and carbon is relatively high. Their performance is very different, nickel iron should belong to alloy steel.
