Abstract
An economic technological mode of dies production according to the scheme: mold surfacing - annealing - mechanical processing - quenching – tempering. The results of research of applying of self-shielding flux-cored wire type (FCADW-SS 100H4M5F2 (Zr)) for punching and trimming dies tool. Punches that surfaced by self-shielding flux-cored wire (FCADW-SS 100H4M5F2 (Zr)) have the hardness within 62-63 HRC after quenching and tempering. Wear resistance of the deposited stamping tool exceeds by 3,5-4 times than the resistance of tool of У8А (U8A) steel and by 1,5-2 times than the resistance of punches of I2XM (12HM) or 9ХМ (9HM) steels, that have the hardness 58 HRC. Established that the flux-cored wire (FCADW-SS 100H4M5F2 (Zr)) allows to ensures high technical and economic impact and achieve economies of expensive high alloying tungsten and tungsten-molybdenum high-speed steels.
