Product Description


Gh4738 High Temperature Alloy Round Pipe
Product Classification : High Temperature Alloy
Material : GH4738
With γ' Nickel based high-temperature alloy with phase precipitation strengthening has good gas corrosion resistance, high yield strength and fatigue performance, good process plasticity, and stable microstructure. Widely used for rotating parts of aircraft engines, with a service temperature not exceeding 815 ºC. This alloy is widely used in aviation engines and gas turbines domestically, mainly as rotating parts such as turbine blades and discs, and has mature usage experience. Due to its high cobalt content, this alloy is rarely used in China.

Application
GH4738 high-temperature alloy is used to make turbine discs, blades, and sealing rings for aviation engines, as well as flue gas turbine blades, turbine discs, and large bolts.
Superalloy is an alloy based on iron, nickel and cobalt, which can work at high temperature above 600 ºC for a long time. It has good oxidation resistance and corrosion resistance, good fatigue performance, fracture toughness and other comprehensive properties, and is widely used in aviation, aerospace, petroleum, chemical industry, ships and ships. Commonly used include gh3030, gh4169, gh4141, gh5188, gh3128, gh4145, and so on.
