A steel in which a deliberate addition of one or more alloying elements, e.g. Mn, Ni, Cr, Mo etc has been made during steelmaking 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 low alloy. The same standard classifies steels which do not meet the minimum requirements as 'non-alloy' steels.
An alloy steel is a steel containing elements other than carbon which have been added to obtain definite mechanical or physical properties, such as higher strength at elevated temperatures, toughness, etc.
An iron based mixture is considered to be an alloy steel when it contains more than 1.65 wt% of Manganese (Mn), 0.5 wt% of Silicon (Si), 0.6 wt% of Copper (Cu) and/or other minimum quantities of alloying elements such as Chromium (Cr), Nickel (Ni), Molybdenum (Mo), or Tungsten (W). Through combining different quantities and types of alloying elements, a wide variety of distinct properties can be produced in steel.
Steel containing elements other than iron and carbon. Note: Manganese is found in all steels in quantities of up to 0.35%. See also: High Speed Steel, Nickel Steel, Stainless Steel.

Steel that, in addition to carbon, contains one or more elements in sufficient amounts to appreciably alter properties compared with those of carbon steel. Materials are alloyed to enhance physical and mechanical properties such as strength, ductility, and hardenability.
An iron-based mixture is considered to be an alloy steel when manganese is greater than 1.65%, silicon over 0.5%, copper above 0.6%, or other minimum quantities of alloying elements such as chromium, nickel, molybdenum, or tungsten are present. An enormous variety of distinct properties can be created for the steel by substituting these elements in the recipe.
Steel is considered to be an alloy steel when either (1) the maximum of the range given for the content of alloying elements exceeds one or more of the following percentages: manganese 1.65, silicon 0.60, copper 0.60; or (2) a definite range or definite minimum quantity of those elements considered alloys is specified. For example, chromium, molybdenum and nickel.
Steel containing substantial quantities of elements other than carbon and the commonly-accepted limited amounts of manganese, sulfur, silicon, and phosphorous. Addition of such alloying elements is usually for the purpose of increased hardness, strength or chemical resistance. The metals most commonly used for forming alloy steels are: nickel, chromium, silicon, manganese, tungsten, molybdenum and vanadium. “Low Alloy” steels are usually considered to be those containing a total of less than 5% of such added constituents.
A steel to which one or more alloying elements other than carbon have been deliberately added (e.g. chromium, nickel, molybdenum) to achieve a particular physical property.
Multi-component alloys of iron, silicon, carbon, chromium, manganese, nickel, sulfur, phosphorus, and lead. Other elements are sometimes, albeit infrequently, used to achieve unusual metallurgical or machinability properties.
Refers to steel that has a substantial content of elements other than carbon and the generally accepted levels of manganese, sulfur, silicon and phosphor. These elements are added to raise the strength, hardness or chemical resistance of the steel.
