Strictly speaking, every steel is an alloy, but not all steels are called “alloy steels”. The simplest steels are iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type). However, the term “alloy steel” is the standard term referring to steels with other alloying elements added deliberately in addition to the carbon. Common alloyants include manganese (the most common one), nickel, chromium, molybdenum, vanadium, silicon, and boron. Less common alloyants include aluminum, cobalt, copper, cerium, niobium, titanium, tungsten, tin, zinc, lead, and zirconium.

Alloy steel casting is the steel casting process that is done with numerous elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low-alloy steels and high-alloy steels. Most commonly, alloy steels used in casting are low-alloy steels. 

Alloy steel castings are metal components made by pouring molten alloy steel into molds to achieve specific shapes and properties. Alloy steel is a blend of iron, carbon, and other elements like chromium, nickel, molybdenum, and vanadium, which enhance its strength, toughness, wear resistance, and corrosion resistance.
