Steel alloy elements such as silicon, manganese, chromium, molybdenum, nickel, vanadium, and boron is known as alloy steel.
With alloy steels of various compositions, hundreds of products can be
made: alloy steel pipes and tubes, alloy steel sheets, plates, and
coils, alloy steel rods, bars, and wires, alloy steel buttweld fittings,
alloy steel forged fittings, alloy steel, fasteners, flanges, and other
alloy steel products. Automobiles, road construction, machinery and
equipment, buildings, mining, railways, appliances, and off-shore
applications are a few of the industries in which alloy steels are used.
