Material Description:
r Solid solution strengthened superalloy, with simple chemical composition, satisfactory thermal strength and high plasticity below ℃, and good resistance to oxidation, thermal fatigue, Cold stamping and welding process performance. The alloy becomes single-phase austenite after solid solution treatment, and the structure is stable during use.
Material usage:
Mainly used for turbine engine combustion chamber components that operate below ℃ and other high temperature components that require oxidation resistance below ℃ but bear small load
