17Cr,7Ni stainless steel containing about 1%Al was experimented upon for determining its mechanical properties after heat treatments such as solution treatment, intermediate quenching and aging at various temperatures and hours. The following results were obtained: (1) The Ms point of this steel is in the range of 150∼0° when it is quenched from 750∼1000°. So this steel may be hardened by water quenching. (2) This steel showed better mechanical properties by aging after solution treatment and intermediate quenching. The highest values were obtained under the following aging conditions; 400°×100 hr, 450°×8∼12 hr, 470°×5∼8 hr and 500°×1 hr.(3) The maximum values of mechanical properties were as follows: tensile strength, about 160 kg/mm2; yielding strength (0.2%) about 120 kg/mm2 and elongation 4∼6%.
