Steel casting is a kind of process which involves casting of various types of steel. Steel castings are mainly used when cast irons can't provide enough strength and stun resistance. Hydroelectric turbine wheels, forging presses, gears, railroad truck frames, valve bodies, pump castings, mining machinery, marine equipment and engine castings are some of the example of high level steel castings.
Steel Castings are mainly categorized into two groups as Carbon Steels and Alloy Steels:
Carbon steel is one with main alloying constituent is Carbon. The American Iron and Steel Institute (AISI) defines carbon steel as: "Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 0.40 percent; or when the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60."
