Alloy Steel contains substantial quantities of elements other than carbon such as nickel, chromium, silicon, manganese, tungsten, molybdenum, vanadium and limited amounts of other commonly accepted elements such as manganese, sulphur, silicon, and phosphorous. Addition of such alloying elements is usually for the purpose to increase hardness, strength or chemical resistance.

Alloy steel is generally categorised into two groups: high alloy steels and low alloy steels. The difference between the two is that the steel that is mixed with more than eight percent of its weight being other elements beside iron and carbon, is high alloy steel. Low alloy steels are slightly more common. The physical properties of these steels are modified by the other elements, to give them greater hardness, durability, corrosion resistance, or toughness as compared to carbon steel. To achieve such properties, these alloys often require heat treatment.

Alloy Steel Tubes are superior strength tubes that are used in daily life, catering to the domestic, professional or industrial needs. In recent years, the demand for alloy steel tubing has been increasing along with the economic growth. These tubes perform exceptionally well under difficult conditions and are thus increasingly being used in many applications.

Alloy steel tubes are generally used for energy-related applications involving oil and gas drilling and is subjected to stresses in machine parts. Other uses of Alloy steel are in aerospace industry, such as in the turbine blades of jet engines and spacecrafts; in nuclear reactors and in transportation. Because of the ferromagnetic properties of iron, steel alloys tubes also find important applications where their responses to magnetism are very important, including in electric motors and in transformers.
