ABSTRACT:
A heat resisting steel consists essentially of 0.005-0.20% of C, 0.01-2.0% of Si, 0.1-2.0% of Mn, 20-30% of Ni, 10-20% of Cr, 3.0-4.5% of Ti and 0.1-0.7% of Al with the ratio Ti/Al being 5-20, and the balance being substantially Fe, which is excellent in the tensile properties at the room temperature and 700.degree. C., and the creep rupture properties at the temperature of 700.degree. C.
