Superalloy
Superalloy refers to a class of iron, nickel or cobalt based metal materials, capable of long-term service under high temperatures above 600℃ and certain stress, and it possesses high temperature resistance, good oxidation and corrosion resistance, good anti-fatigue properties, fracture toughness and other comprehensive properties. Our company's main superalloy products include: Inconel 718 forged and hot rolled round bars applied to gas turbine, petroleum, aerospace; N90 forged bars applied to aerospace, N80A flat bars and forged bars; Incoloy 901 stepped shaft forgings applied to steam turbines as well as other various superalloy forged bars, rolled rounds and forgings for aviation, aerospace and gas turbine applications.
