Product FEATURE
17-4PH ndeye chromium-nickel-mhangura kunaya inoomesa martensitic simbi isina tsvina. Iri giredhi resimbi isina tsvina rinoratidzwa nesimba rakawanda, kuoma uye kusagadzikana kwemarara. Iyo mechanical properties inovandudzwa nekupisa Kurapa uye kudzvinyirira masimba anosvika 1100-1300 MPa (160-190 ksi) inogona kuwanikwa. Giredhi iri harigone kushandiswa patembiricha iri pamusoro pe300°C (572°F) kana pakudzikira kwakadzikira. Iyo ine yakanaka corrosion resistance kumhepo uye dilute acids kana munyu, uye kushora kwayo kunofananidzwa ne304.
17-7PH is austenitic-martensitic precipitation inoomesa simbi isina tsvina yakagadzirwa pahwaro hwe18-8CrNi, inozivikanwawo seyakadzorwa chikamu shanduko simbi isina tsvina. 17-7PH Stainless simbi isingagadzike austenitic sangano pashure yakasimba mhinduro Kurapa, pamwe yakanaka epurasitiki kuomarara uye machinability, pashure tempering, kuitira kuti austenite precipitation pamusoro carbides pashure kuchinjwa kuumbwa, uye ipapo kuburikidza martensitic shanduko muitiro, vazhinji vesangano rinoshandurwa kuva yakaderera kabhoni tempering muitiro pamwe kuoma zvakanaka. Mushure mekudzikamisa, iyo austenite precipitation carbide kuumbwa kunoshanduka, uyezve kuburikidza neiyo martensitic shanduko maitiro, mazhinji esangano anoshandurwa kuita yakaderera kabhoni tempered martensite nekusimba kwakanaka, uye ine yakanaka mechanical zvivakwa pane yepakati tembiricha. 17-7PH corrosion resistance iri nani pane general martensitic stainless simbi.
