Kunaya kunoomesa simbi isina tsvina, inodaidzwa kuti PH Steel, inoreva rudzi rwesimbi isina nguraiyo inowedzera marudzi akasiyana-siyana uye huwandu hwekusimbisa zvinhu, uye marudzi akasiyana uye huwandu hwecarbides, nitrides, carbonitrides uye intermetallic compounds zvinoputirwa kuburikidza nekunaya kwemvura kuomesa maitiro. Kunaya kunoomesa simbi isina tsvina hakungove nesimba rakakwirira chete, asiwo kune kusimba kwakanaka uye kusaita ngura. Kunaya kunoomesa simbi isina tsvina kunogona kukandwa kwatiriInvestment casting foundrymaererano nemadhirowa ako, zvinodiwa uye mamiriro ekushandisa.
Zvinoenderana nezviri mukati meiyo main alloy element mukunaya kwemvura inoomesa simbi isina tsvina uye yakawedzera kuomesa zvinhu, kunaya kwemvura kuomesa simbi isina simbi inogona kupatsanurwa muzvikamu zvina mune zvinotevera:
(1)Martensitic Precipitation Kuomesa Stainless Simbi. Iyo inowanzo ine kabhoni isingasviki 0.1%. Simbisa nekuwedzera kuomesa zvinhu (mhangura, aruminiyamu, titanium uye aluminium, nezvimwewo) kugadzira kushayikwa kwesimba. Izvo zvemukati zvechromium zvinowanzokwira kupfuura 17%, uye huwandu hwakakodzera hwenickel hunowedzerwa kuti uvandudze kuramba kwecorrosion.
(2)Kunaya Kwemvura Kuomesa Stainless Simbi, ine kabhoni yemukati isingakwire kupfuura 0.03% kuti ive nechokwadi chekuoma, kuonda kuramba, weldability uye kushanda kweiyo martensite matrix, uye 12% chromium kuve nechokwadi chekuonda. Mukuwedzera, iyo alloy element cobalt inowedzerwa kuti iwedzere kuvandudza kupisa kwekupisa kwesimbi.
(3)Semi-Austenitic Precipitation Kuomesa Stainless Simbi, kureva, kunaya kwekuchinja kunoomesa simbi isina tsvina, ine isingasviki 12% chromium. Iyo ine yakaderera kabhoni yemukati, uye aluminium seyayo huru yekunaya inoomesa chinhu. Kunaya kwemvura kunoomesa simbi isina simbi kune kuita kurinani pane kunaya kwemartensitic kunoomesa simbi isina simbi.
(4)Austenitic Precipitation Kuomesa Stainless Simbiisimbi isina tsvina ine yakagadzikana austenite chimiro mune zvese zvakadzimwa uye kuchembera nyika. Iyo nickel yemukati uye manganese yemukati yakakwira, uye iyo chromium yemukati yakakwira kupfuura 13% kuti ive nechokwadi chekuramba kwecorrosion uye oxidation kuramba. Panguva imwecheteyo, austenitic precipitation inoomesa simbi isina tsvina inowanzowedzera titanium, aruminiyamu, vanadium kana phosphorus semvura inoomesa zvinhu, uye inowedzera hushoma hweboron, vanadium, nitrogen nezvimwe zvinhu kuti uwane zvakanakisa zvivakwa.
Kunaya kunoomesa simbi isina tsvina inoshandiswa zvakanyanya mumaindasitiri epamusoro. Semuyenzaniso, kunaya kwakajairwa kuomesa simbi isina simbi 17-4PH inogona kushandiswa kugadzira zvimiro zviri pasi pe 370°C zvinoda kusaita ngura, kusapfeka, uye simba guru.
