Hastelloy G50

Super alloys or high performance alloys have the capacity to function at hightemperatures and extreme mechanical stress, and also where high surface stability isrequired. They are available in different shapes, and have good creep and oxidationresistance. Solid­solution hardening, work hardening, and precipitation hardening areperformed for improving strength of this alloy.Hastelloy(r) G50(r) is a nickel­chromium­molybdenum and iron alloy. The followingdatasheet gives an overview of hastelloy(r) G50(r).
