About ATI Inc.
ATI Inc. is a publicly listed US company headquartered in Dallas, Texas, with approximately 7,312 employees worldwide. The company produces and processes high-performance materials such as titanium and titanium alloys, nickel- and cobalt-based superalloys, stainless and specialty steels as well as reactive and refractory metals such as zirconium, hafnium, niobium and tantalum. The value chain is vertically integrated: from sponge production via melting processes (AOD, ESR, VIM, VDIP, VAR), hot and cold rolling, forging (isothermal, hot-die, closed-die, ring rolling), powder metallurgy and additive manufacturing to CNC machining, assembly, heat treatment and testing. Products include long products (ingot, billet, bar, pipe), plate, sheet and foil as well as precision-forged and machined components such as compressor and turbine disks, rings, shafts and helicopter rotor components. Key customers are aerospace, defense, oil and gas, chemical industry, energy technology including nuclear power as well as medical technology; long-term contracts exist with Boeing and Airbus. With 57 sites in 17 countries, ATI manufactures in the USA and Europe (including the forging plant Stalowa Wola, Poland) and distributes via offices in Asia, Europe and the Americas. In Germany, ATI is represented by ATI Materials GmbH in Düsseldorf.
