Steel Alloys

摘要

Steel castings are used in a variety of end-use applications that require heavy-duty components. The castings are used for components of railroad cars, pumps, valves, heavy trucks, construction and mining equipment, and power generation units. A good steel casting application requires strength and utilizes the flexible geometry inherent in the metalcasting process. Steel castings offer mechanical properties over a wide range of operating temperatures and environments, some of which can be corrosive. Further, cast steel will generally offers advantages of cost, weight and dimensional accuracy over wrought steel, which has to be welded to use multiple pieces to produce parts of the same configuration.
