Nhanganyaya
Giredhi 316 ndiyo giredhi repamusoro rine molybdenum, riri rechipiri pakukosha kune 304 pakati pesimbi dzisina ngura dzinoshandiswa austenitic. Molybdenum inopa hunhu huri nani hwe316 hunodzivirira ngura pane Giredhi 304, kunyanya kusimba kwakanyanya kukudzivirira ngura inoputika uye inotsemuka munzvimbo dzine chloride.
Giredhi 316L, iyo ine kabhoni shoma ye316 uye haina kukanganiswa nekupisa (kunaya kwecarbide kubva muzviyo). Saka inoshandiswa zvakanyanya muzvikamu zvakasungirirwa zvine gauge yakawanda (inopfuura 6mm). Kazhinji hapana musiyano wemutengo unozivikanwa pakati pe316 ne316L simbi isina ngura.
Maumbirwo e austenitic anopawo kusimba kwakanaka kwemhando idzi, kunyangwe kusvika pakupisa kwakanyanya.
Zvichienzaniswa nesimbi dzisina ngura dzinonzi chromium-nickel austenitic, simbi isina ngura ye316L inopa simba rakawanda rekukwira, kushushikana kusvika pakutsemuka uye simba rekusimba pakudziya kwakakwirira.
Zvimiro Zvikuru
Hunhu uhwu hwakatsanangurwa kune chigadzirwa chakapetwa chakati sandara (plate, sheet uye coil) muASTM A240/A240M. Hunhu hwakafanana asi husiri hwechokwadi hwakatsanangurwa kune zvimwe zvigadzirwa zvakaita semapaipi nebhawa muzvirevo zvazvo.

317L
Kudzivirira machloride kwakanyanya kupfuura 316L, asi kuchidzivirirawo ngura yakawandisa.
Kuramba Kuora
Yakanaka kwazvo munzvimbo dzakasiyana-siyana dzemumhepo uye munzvimbo dzakawanda dzinopisa - dzinowanzo dzivirira kupfuura 304. Dzinogona kukanganiswa nekuora munzvimbo dzinodziya dzechloride, uye dzinopwanyika nekuora kupfuura 60 degrees.°C. Inoonekwa seisingapindi mvura inonwiwa ine machloride anosvika 1000mg/L patembiricha yekunze, ichiderera kusvika pa500mg/L pa60°C.
316 inowanzoonekwa sechiyero"simbi isina ngura yemhando yegungwa"", asi haidzivirirwe nemvura inodziya yegungwa. Munzvimbo zhinji dzegungwa 316 inoratidza ngura pamusoro, inowanzoonekwa semavara ebrown. Izvi zvinonyanya kukonzerwa nemakomba uye kupenya kwepamusoro.
Kuramba Kupisa
Kudzivirira kwakanaka kwe oxidation mukushanda kwepakati kusvika ku870°C uye iri kushanda nguva dzose ku925°C. Kushandiswa nguva dzose kwe316 mu425-860°Chiyero cheC hachikurudzirwi kana kuramba kwemvura kuchikosha. Chiyero che316L chinodzivirira mvura kubva mucarbide uye chinogona kushandiswa muchimiro chekupisa chataurwa pamusoro apa. Chiyero che316H chine simba rakawanda pakupisa kwakakwira uye dzimwe nguva chinoshandiswa pakushandiswa kwechimiro uye kudzvanywa pakupisa kuri pamusoro pe500°C.
Kurapa Kupisa
Kurapa Mhinduro (Kunyungudutsa) - Kupisa kusvika 1010-1120°C uye inotonhorera nekukurumidza. Magiredhi aya haagoni kuomeswa nekupisa.
Kushongedza
Kugona kupinza zvakanaka kuburikidza nenzira dzese dzakajairwa dzekubatanidza uye dzekudzivirira, zvese nesimbi dzekuzadza uye dzisina. Zvikamu zvakasungirirwa zvakanyanya muGiredhi 316 zvinoda annealing mushure mekupinza kuti dzisanyanya kupinza ngura. Izvi hazvidiwi pa316L.
Simbi isingasvibiswi ye316L haiwanzo svetwa uchishandisa nzira dzekubatanidza dzeoxyacetylene.
Kugadzira michina
Simbi isina ngura ye316L inowanzo shanda nesimba kana ikashandiswa nekukurumidza. Nekuda kweizvi, kumhanya kwakaderera uye mwero wekudya nguva dzose zvinokurudzirwa.
Simbi isingasvibi 316L iri nyorewo kugadzira kana tichienzanisa nesimbi isingasvibi 316 nekuda kwehuwandu hwayo hushoma hwekabhoni.
