The authors described the effect of carbon, silicon mangan and nickel on the aging of heat resisting steel of Ni-Cr system, in the previous report. (Tetsu-to-Hagane vol.39, 1953, ) In the present investigation, they examined the effect of chromium, tungsten, molybden and tungsten plus molybden on aging of the same heat resisting steel of Ni-Cr system containing Ni 15%, Cr 20% as in the previous investigation. As the results of these experiments, the authors gave most moderate contents of Cr, W and Mo, and then heat treatment for Ni-Cr austenitic heat resisting steel, concluding that : (1) The moderate contents of Cr were 20∿25% for Ni 15∿20% heat resisting steel, (2) W 4∿6%, Mo 5∿7% or W+Mo (3+5)%∿(5+4)% were the moderate content for Ni 15%, Cr 20% steel, (3) Temperature of the solution treatment were 1200∿1250C, and aging temperature were 750∿800℃, and then aging time were 6∿12 hours for Ni-Cr austenitic heat resisting steels containing W, Mo or W+Mo
