Inconel 738 Round Bar Tube Sheet Nickel Alloy Wire
KX Inconel 738 Nickel Alloy Wire Round Bar Tube Steel Sheet Light Rod on Inconel Alloy
Product Description and Application
Inconel738 is also known as GH4738, Inconel738Waspaloy(USA), NC20K14(France)
Inconel738 is that Ni-Cr-Co Precipitate-hardening deformed superalloy, the use temperature is below 815℃. Cobalt, chromium and molybdenum are added to the alloy for solution strengthening, aluminum and titanium are added to form γ’ phase, boron and zirconium are added to purify and strengthen the grain boundaries. The alloy has high yield strength and fatigue resistance at 760℃~870℃. It has high oxidation resistance and corrosion resistance in gas turbine atmosphere below 870℃.
