Insimbi engagqwali engu-15-5 PH iyinsimbi engenasici enemvula eqinile ene-martensitic ene-Chromium engu-15% ne-5% Nickel. Inamandla aphezulu, ubulukhuni obuphezulu, nokumelana nokugqwala okuhle kakhulu. Amandla angandiswa ngokuqhubekayo ngokwelashwa okukodwa kokushisa okuphansi. Uma kuqhathaniswa ne-17-4 PH, inikeza ukuqina okungcono okuphambene kanye ne-ductility; izakhiwo ezingcono zemishini ezigabeni ezinkulu eziphambanayo, kanye nokwenzaka kangcono. Ishelela kalula. Ingenziwa ngomshini kunoma yiziphi Izimo Ezishisayo ezimbalwa ezitholakalayo kuleli banga.
