what are the typical features of these three kinds of steel!

 Cast steel is iron, carbon as the main elements of the alloy, carbon content is 0-2%. Cast steel is divided into cast carbon steel, cast low alloy steel and special steel casting 3 classes. Below, we take a look at what are the typical features of these three kinds of steel!

1, in order to meet the special needs and refining alloy cast steel,cast is a great variety of special steel, usually contains high amount of one or more alloying elements, in order to obtain some kind of special performance. For example, high manganese steel containing 12% ~ 15% manganese can impact wear, many wearing parts used in mining machinery, engineering machinery; Chromium or nickel chrome as the main alloying elements of all kinds of steel, used to have a corrosion or high temperature above 650 ℃ under the condition of working parts, such as chemical in the body, pump, the container or the large capacity power plant steam turbine casing, etc.
2, with carbon as the main alloying elements and contain small amounts of other elements in the cast steel is molten carbon steel. Carbon is less than 0.2% for casting low carbon steel, carbon is 0.2% ~ 0.5% for medium carbon steel casting, carbon is more than 0.5% for casting high carbon steel. With the increase of carbon content, increase the strength of the casting of the carbon steel, hardness is improved. Casting of the carbon steel has high strength, plasticity and toughness, low cost, in the heavy machinery used in the manufacture of high load of parts, such as rolling mill frame and press the base; On railway vehicles used in the manufacture of force big and withstand the shocks of bolsters and side frames, wheels and components such as coupler, etc.
(3), contains the alloying elements such as manganese, chromium, copper, cast steel is cast low alloy steel. Total alloying elements generally less than 5%, has a larger impact toughness, and can get better mechanical properties by heat treatment. Cast low alloy steel than the use of carbon steel has a better performance, can reduce the parts quality, improve the service life.
