17-4PH Izinto eziphathekayo
I-17-4PH yi-chromium-nickel-copper precipitation eyenza lukhuni intsimbi ye-martensitic.Eli bakala lensimbi engenasici lineempawu ezinjengokuqina okuphezulu, ukuqina kunye nokumelana nokubola.Emva kokunyanga ubushushu, iipropathi zomatshini zemveliso zigqibelele ngakumbi, kwaye amandla oxinzelelo anokufikelela phezulu njenge-1100-1300MPa (160-190ksi).Eli bakala alinakusetyenziswa kumaqondo obushushu angaphezu kwama-300°C (572°F) okanye aphantsi kakhulu.Inokumelana ne-corrosion efanelekileyo kwi-atmospheric kunye ne-dilute acids okanye iityuwa.Ukuxhathisa kwayo kuthelekiseka ne-304. Magnetic.
