Alloy Steel is a super alloy made of varying quantities of multiple elements such as nickel, chromium, silicon, manganese, tungsten, molybdenum, vanadium and limited amounts of other 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. In comparison to other steels, Alloy steel shows improved properties such as greater strength, more toughness and hardness, great wear resistance and stronger corrosion resistance.

Alloy steels are thus used in the turbine blades of jet engines, in spacecraft, and in nuclear reactors. Due to the ferromagnetic properties of iron, some steel alloys find important applications where their responses to magnetism are very important, such as in electric motors and in transformers.


Alloy steel pipes are made of alloy steel and hold excellent properties. These pipes are majorly favoured because of their resistance to corrosion and oxidation. They are generally used for energy-related applications like oil and gas drilling and are subjected to stresses in machine parts. Alloy Steel Pipes are extensively used for conveyance of fluids intended for critical high temperature and general corrosion service applications.

Alloy Steel Pipes are also made use of in boiler tubes and heat-exchanger tubes and are available with different surface treatment options like pickled and annealed/polished, galvanized and others. Some of its features include option of different metal grades; application suitability in areas like water supply, chemical industry, aviation and others.
