| titleOfInvention | Heat treating method for hardening type stainless steel and coupler manufacturing method using the same |
| abstract | (a) by weight %, Ni: 3.0 to 5.0%, Cr: 15.5 to 17.5%, C: greater than 0 0.07% or less, Cu: 3.0 to 5.0%, Nb+Ta: greater than 0 0.45%, Mn: greater than 0 1.0 % or less, Si: greater than 0 and less than or equal to 1.0%, the remaining Fe and the steps of kneading a metal powder and a binder composition containing unavoidable impurities to prepare a mixture, (b) injection molding the mixture to form a coupler, (c) ) Degreasing the injected coupler, (d) sintering the degreased coupler, and (e) heat-treating the sintered coupler at a temperature of 420 to 540 ° C. A method for manufacturing a coupler using the same is provided. The method for heat treatment of precipitation hardening stainless steel and the method for manufacturing a coupler using the same according to the present invention are characterized in that they have excellent mechanical properties through MIM (Metal Injection Mold) method and heat treatment. |
