Precision casting three characteristics

Precision casting three characteristics

Steel casting is iron, carbon, as the main element of the alloy , the carbon content of 0-2 % . Divided into cast carbon steel , low alloy steel casting and casting of special steels in Class 3. Here, we take a look at what are the three types of castings characteristics of it !
1.In order to meet the special needs refining of alloy steel is cast a wide variety of special steel , usually containing one or more of the high amount of alloying elements to obtain a particular performance . For example, manganese 12% to 15 % of high impact wear resistant manganese steel , used for mining machinery, engineering machinery wear parts ; chromium or chromium -nickel as the main alloying elements of the various steel castings, for corrosion or high temperature above 650 ℃ under the conditions of working parts, such as the chemical industry valve , pump , container, or large-capacity power plant turbine housing and so on.
2.With carbon as the main alloying element and contains small amounts of other elements of the steel is cast carbon steel . Carbon content of less than 0.2 % for casting low carbon steel, carbon 0.2 % to 0.5% for the casting of carbon steel, carbon greater than 0.5 % for casting high-carbon steel . As the carbon content increases, the strength of cast steel , the hardness increased . Cast carbon steel with high strength , ductility and toughness , low cost, in the heavy machinery used in the manufacture of parts to withstand large loads , such as rolling mill frame, hydraulic base, etc. ; in railway vehicles for the manufacture of large force and parts to withstand shocks such as bolsters , side frames , wheels and couplers, etc.
3.Contains manganese , chromium, copper and other alloying elements of steel is low alloy steel casting . Alloying elements are generally less than 5% , with a larger impact toughness , and heat treatment to obtain better mechanical properties. Casting low alloy steel with optimum use of performance, can reduce part quality , improve service life.
