The GH4145 nickel alloy is same to Inconel X-750 but made precipitation hardenable by adding aluminum and titanium and thereby shows excellent resistance to high temperature corrosion and oxidation along with high tensile and creep-rupture strength, relaxation resistance as well as good fabricating and welding properties.


GH4145 Sheet
The GH4145 Pipe also has outstanding mechanical properties down to cryogenic temperatures. With such properties, the nickel-chromium alloy is mainly used for high-temperature springs and bolts, gas turbine blades, rocket engines, abrasion wheels, high pressure vessels, etc.
