The author studied as follows : (1) The influences of Cr, Ni, W, Mo, V, Ti, Cu of the high Mn-Cr steels on the high temperature (up to 800℃) mechanical properties of the high Mn-Cr steels, at the same time, for reference, on some of decrease of toughness when kept at about 700℃ after quenched from 1050℃ and on the scaling. (2) The effect of Ti of the high Mn-Cr-W-Mo steels on the decrease of toughness, not only at the room temperature, but also at the high temperature up to 700℃, when kept for long time at 750℃ after quenched from 1050°and 1200℃. (3) The influences of C and V of the high Mn-Cr steels on the hardness and the shock value when quenched from 1000∿1200℃ and tempered at 500∿800℃. (4) The influences of the conditions of every heat-treating process of the high Mn-Cr-V steels. (5) Additional remarks ; The influences of V and Ti of 14% Cr-14% Ni-W steels on the shock value and the hardness when heated at 1000∿1350℃ and when kept for long time at 750℃ after quenched from 1100 and 1200℃.
