Alloy steel is a type of steel that contains other elements such as nickel, chromium, molybdenum, vanadium, and tungsten, in addition to carbon and iron. These alloying elements impart specific properties to the steel, such as increased strength, hardness, and resistance to wear and corrosion. Here is a brief description of Taksh Steel India's alloy steel pipe, tube, flange, fastener, fittings and round bar range:
