Superalloys are heat resistant alloys based on nickel (Ni) iron-nickel (Fe-Ni) or cobalt (Co) that exhibit a combination of mechanical strength and resistance to surface degradation at elevated temperatures that is unmatched by other metallic alloys. Superalloys are primarily used in gas turbines, coal conversion plants and chemical process industries as well as other specialized applications requiring high heat and corrosion resistance. The three types of superalloys are further subdivided into wrought, cast and powder metallurgy alloys. Cast alloys can be further broken down into polycrystalline, directionally solidified and single-crystal superalloys. The production and casting of superalloys requires processing within a vacuum or controlled atmosphere environment.
Ajax TOCCO designs and manufactures custom systems for the production and casting of superalloys.
