There are often numerous alloy steels used for fasteners, though the specific one for your needs depends on which special element is added to the steel in order to achieve the desired effect. Different combinations of alloy elements gives the steel all the functions of the added element.
For instance, manganese alloy has higher strength, and manganese helps to increase the surface quality of steel. If the copper content exceeds 0.20%, it facilitates the production of an air corrosion resistance. In addition, molybdenum, boron, nickel and other elements are also available in alloy steel.
