17-4PH ANNEALED Stainless zitsulo

Aloyi 17-4 ndi mpweya wa chromium-copper woumitsa chitsulo chosapanga dzimbiri chomwe chimagwiritsidwa ntchito pofunikira mphamvu yayikulu komanso kukana kwa dzimbiri. Ndi imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri kuti mvula ikhale yovuta kwambiri, chifukwa imakhala ndi mphamvu zolimba kwambiri mpaka pafupifupi 572 ° F pamene ikuwonetseratu kukana kwa dzimbiri muzochitika zonse zomwe zimatenthedwa ndi kutentha. Aloyi 17-4 imakhala ndi kukana kokwanira kwa mlengalenga kapena mumchere wosungunuka wa asidi komwe kukana kwake kwa dzimbiri kumakhala kofanana ndi Aloyi 304 kapena 430. Aloyi 17-4 ikhoza kutenthedwa ndi kutentha kosiyanasiyana kuti ikhale ndi katundu wambiri. Zochita zake zamakina zimatha kukonzedwa ndi chithandizo cha kutentha komwe mphamvu zokolola zambiri mpaka 180 ksi zingapezeke. Aloyi 17-4 sayenera kugwiritsidwa ntchito pa kutentha pamwamba pa 572 ° F kapena kutentha kwambiri.

17-4 Chitsulo chosapanga dzimbiri
Mvula ya martensitic iyi yomwe imaumitsa chitsulo chosapanga dzimbiri imakhala ndi kuuma kwakukulu ndi mphamvu pambuyo pa chithandizo choyenera cha kutentha. Ilinso ndi dzimbiri ndi kutentha kofanana ndi Giredi 304. Mawu awiri akuti "Type 630" ndi "17-4PH" amatanthauza giredi yomweyo.
