17-4PH Izinto ezibonakalayo
I-17-4PH iyimvula ye-chromium-nickel-copper eqinisa insimbi engagqwali ye-martensitic.Leli banga lensimbi engagqwali linezakhiwo ezinjengamandla aphezulu, ubulukhuni nokumelana nokugqwala.Ngemuva kokwelashwa kokushisa, izakhiwo zemishini zomkhiqizo ziphelele kakhulu, futhi amandla okucindezela angafinyelela phezulu njenge-1100-1300MPa (160-190ksi).Leli banga alikwazi ukusetshenziswa emazingeni okushisa angaphezu kuka-300°C (572°F) noma aphansi kakhulu.Inokumelana nokugqwala okuhle komkhathi futhi ihlanza ama-acids noma usawoti.Ukumelana nokugqwala kwayo kuqhathaniswa no-304. Magnetic.
