Power generation combines high temperature, pressure and corrosion, from gas-turbine hot sections to steam and flue circuits. Langley supplies high-strength nickel alloys such as Alloy 718 and Alloy 625, with duplex and super duplex grades where strength and corrosion resistance are needed together.
