15-5 simbi isina tsvina ndeye martensitic, kunaya-kuomesa zvinhu zvine chromium, nickel nemhangura. Inowanzova sarudzo yekutanga muindasitiri yeaerospace yezvitsigiro uye zvimiro zvemuviri. Chimiro chayo chakasarudzika chinopa kuomarara kwakawedzera uye kuramba kwecorrosion kuri nani pane yakatangira, 17-4 PH. Zvese zviri zviviri kudzora kudzora uye hushoma huwandu hwedelta ferrite kana zvichienzaniswa ne17-4 simbi isina tsvina inobatsira mukuoma kukuru kwe15-5. Iyo alloy inosimbiswa zvakare neyakaderedzwa tembiricha kupisa kurapwa iyo inokonzeresa mhangura ine chikamu mune alloy. 15-5 PH inokwanisa kusangana neyakaomesesa mechanicha zvinhu zvinodiwa muaerospace uye maindasitiri enyukireya.
