Alloy Steels are basically carbon steels with certain chemical elements added to improve the properties of the metal for specific applications or end products. Alloying elements include carbon, copper, sulfur, manganese, phosphorus, and chromium, and the resulting material is called an alloy steel. We provides alloy steel in all mill forms including sheet, strip, plate, foil, round bar, square bar, flat bar, hex bar, tube, pipe and wire. Alloy steel is steel alloyed with a variety of elements in total amounts of between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels.
