Alloy Steels

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. All Metals & Forge provides alloy steel in all mill forms including sheet, strip, plate, foil, round bar, square bar, flat bar, hex bar, tube, pipe and wire. Please see our complete list of alloys shown below.

AM&F also supplies alloy steel custom hand-rolled bar in rounds, flats, square, hex and custom shapes up to 2 ¼ inch (57.15 mm), as well as in between sizes that are not commercially available.
Please see our Forging Capabilities Chart for information on alloy steel forgings. Alloy steel forged products include blocks, bars, shafts, disks, hubs, flanges, rings, seamless rolled rings, seamless contoured rolled rings.
If you need a custom or controlled chemistry, AM&F can provide vacuum melting quantities from 250 to 25,000 pounds. Please see our custom melting section for more information.
For value-added services, such as cold and hot forming, heat treating, cutting, machining, rolling and welding, please see our Value-Added Services section.
