Abstract: A high creep-resistant equiaxed grain nickel-based superalloy. The high creep-resistant equiaxed grain nickel-based superalloy is characterized that the chemical compositions in weight ratios include Cr in 8.0 to 9.5 wt %, W in 9.5 to 10.5 wt %, Co in 9.5 to 10.5 wt %, Al in 5.0 to 6.0 wt %, Ti in 0.5 to 1.5 wt %, Mo in 0.5 to 1.0 wt %, Ta in 2.5 to 4.0 wt %, Hf in 1.0 to 2.0 wt %, Ir in 2.0 to 4.0 wt %, C in 0.1 to 0.2 wt %, B in 0.01 to 0.1 wt %, Zr in 0.01 to 0.10 wt %, and the remaining part formed by Ni and inevitable impurities.
