17-4PH Zvinhu Zvekushandisa
17-4PH ndeye chromium-nickel-mhangura kunaya inoomesa martensitic simbi isina tsvina.Iri giredhi resimbi isina tsvina rine zvimiro zvakaita sesimba rakakwirira, kuomarara uye kushora.Mushure mekupisa kwekupisa, maitiro emagetsi echigadzirwa anowedzera kukwana, uye simba rekumanikidza rinogona kusvika kusvika pa1100-1300MPa (160-190ksi).Giredhi iri harigone kushandiswa patembiricha inodarika 300°C (572°F) kana yakaderera zvikuru.Iyo ine yakanaka corrosion resistance kumhepo uye dilute acids kana munyu.Kuramba kwayo kwegora kunofananidzwa ne304. Magnetic.
