Changjin is capable to manufacture tailored alloy steel forging rings designed to meet specific customer requirements. Our High technology quenching systems along with our forging processes allow us to manufacture high quality alloy steel forgings in a wide range of shapes, including rolled cube, rings, bars, blocks, discs and more.
Depending on the chemistry and manufacturing process, Alloy Steel Forged Rings are benefits that can be exhibited: Wear resistant, Toughness and hardenability, High strength at high and low temperatures, Corrosion Resistant, Good machinability.
Alloy steel grades come in various forms, including sheets, plates, bars, and pipes, offering versatility in design options.
