15-7M0Ph ibyuma birashobora kwihanganira ubwoko bwose bwubukonje no gusudira muburyo bwa austenite.Noneho binyuze mubushuhe burashobora kubona
imbaraga zisumba izindi;Munsi ya 550 ℃ hamwe nubushyuhe buhebuje bwo hejuru, yashizweho kugirango igire ubukana burenze 17-4 PH.Amavuta ya martensitike mu miterere yimiterere kandi arashimangirwa no kuvura ubushyuhe buke ugereranije no kugabanya umuringa urimo icyiciro.

•Irashobora kwihanganira ubwoko bwose bwubukonje no gusudira muburyo bwa austenite.none binyuze mumashanyarazi arashobora kubona hejuru
imbaraga, Munsi ya 550 ℃ hamwe nubushyuhe buhebuje bwo hejuru.
•Ibikoresho byo gusudira amashanyarazi steel Ibyuma birashobora gukoresha gusudira arc, gusudira birwanya hamwe na gaze ikingira arc gusudira, gusudira gaze ikingiwe nibyiza.
Kuzenguruka akenshi bikorwa mubikoresho bikomeye byo kuvura, kandi ntukeneye gushyuha mbere yo gusudira.
Iyo gusudira bisaba imbaraga nyinshi, 17-7 hamwe nibiri munsi ya fer- ferrite ihitamo ahanini, insinga yo gusudira ibyuma ya austenitis irashobora gukoreshwa
Bikoreshwa mugukora indege yoroheje-urukuta rw'ibikoresho, ubwoko bwose bwibikoresho, imiyoboro, isoko, isoko ya valve, ubwato bwubwato,
plaque compressor, ibice bya reaktor, kimwe nibintu bitandukanye bigize imiterere yibikoresho bya shimi, nibindi.
