L-605

UNS #R30605

L-605 is a nonmagnetic, chromium-nickel-tungsten-cobalt alloy possessing good oxidation and corrosion resistance as well as high strength properties at elevated temperatures. The high strength properties of this alloy may be obtained through work hardening, and it remains nonmagnetic in this condition. Although the aging response of L-605 is considered minimal when compared to typical age hardening alloys, it may be used in the cold worked and aged condition in certain instances. L-605 is generally melted using vacuum induction melting (VIM), followed by electroslag remelting (ESR). The finished mill product is supplied in the solution annealed or cold worked condition, depending on section size and application.
