Alloy Steel
Alloy Steel

A steel in which a deliberate addition of one or more alloying elements, e.g. Mn, Ni, Cr, Mo etc has been made during steel making to enhance the properties of the steel. The amounts of each element that must be present in steel before it is classified as an alloy steel are given in Table 1 in BS EN 10020: 1998. At low levels of addition the steels may be classified as micro or low alloy. The same standard classifies steels that do not meet the minimum requirements as ‘non-alloy’ steels.
