Alloy Steel Castings
Alloy steel is a group of alloy which mainly consist iron, carbon and other alloyed elements such as Si, Mg, Cr, Mo, Ni, Mn, Cu etc. Cast alloy steel can be divided into cast low alloy steel (the total alloy elements are less than or equal to 5%), cast alloy steel (the total alloy elements are 5% to 10%) and cast high alloy steel (the total alloy elements are greater than or equal 10%). Based on different applications and structure, alloy steel can be cast by many kinds of casting processes including investment casting, sand casting, shell casting, lost foam casting and vacuum casting. The alloy steel castings usually have some unique mechanical properties such as heat resistance, wear resistance, stainless and corrosion resistance.
