Alloy Steel Pipe HastelloyX
Hastelloy X is a kind of nickel-based superalloy with high iron content, which is mainly solution strengthened by chromium and molybdenum solution strengthening. It has good resistance to oxidation and corrosion resistance. It has good cold & hot formability and weldability because its moderate lasting and creep strength under 900℃. Used in the manufacture of aircraft engine combustion chamber components and other high temperature components. It can be long-term used under 900℃, and short-term working temperature can up to 1080℃.
Similar Grade of Hastelloy X: GH3536, GH536,GH22, GH334, GH739, SG-5, UNS N06002, NC22FeD, NiCr22FeMo, Nimonic PE13, Hastelloy H
Application for Hastelloy X: Used in the manufacture of aircraft engine combustion chamber components and other high temperature components
