17-4PH Zinthu Zakuthupi
17-4PH ndi mpweya wa chromium-nickel-copper woumitsa chitsulo chosapanga dzimbiri cha martensitic.Gulu lachitsulo chosapanga dzimbiri lili ndi zinthu monga mphamvu zambiri, kuuma komanso kukana dzimbiri.Pambuyo pa chithandizo cha kutentha, makina opangira mankhwala ndi abwino kwambiri, ndipo mphamvu yopondereza imatha kufika pamtunda wa 1100-1300MPa (160-190ksi).Gululi silingagwiritsidwe ntchito pa kutentha kuposa 300 ° C (572 ° F) kapena kutsika kwambiri.Ili ndi kukana bwino kwa dzimbiri kumlengalenga ndikuchepetsa ma acid kapena mchere.Kukana kwake kwa dzimbiri ndikufanana ndi 304. Magnetic.
