Alloy Steel is alloyed with a variety of elements ranging between 1.0%-50% content, when compared to the total weight. Some of the commonly alloyed elements of alloy steel include manganese, nickel, molybdenum, chromium, vanadium, silicon, and boron. Along with this some lesser alloyed elements are cobalt, copper, zirconium, cerium, titanium, tungsten, tin, zinc, niobium, lead and zirconium.
Though every steel is an alloy, but not all steels are named “Alloy Steels”. Alloy steel find has many properties that come along with the addition of alloyants. Strength, toughness, hardness, wear resistance, corrosion resistance, and hardenability. Alloy steel is used in many exotic applications like jet engine parts, Spacecraft parts and even in nuclear reactors. Electric motors in transformers are made from steel alloys owing to the ferromagnetic properties of iron in them. Alloys steels are also more responsive when it comes to mechanical treatments, as compared to carbon steel.
