Nta ntawm Duplex Ss 2205
2205 stainless hlau 4 * 1mm capillary coiled tubing
Duplex Stainless Steel 2205 Piv nrog 316L thiab 317L austenitic stainless hlau, 2205 yog superior hauv kev tiv thaiv pitting thiab crevice corrosion kuj.Nws muaj siab corrosion kuj.Piv nrog austenite, nws cov thermal expansion coefficient qis dua, thermal conductivity yog siab dua.
Duplex Stainless Steel 2205 muaj ob zaug lub zog compressive ntawm austenitic stainless hlau, tso cai rau cov tsim kom txo tau lawv qhov hnyav piv rau 316L thiab 317L.Lub 2205 alloy yog tshwj xeeb tshaj yog haum rau siv nyob rau hauv lub -50 ° F / + 600 ° F kub ntau yam thiab yuav siv tau rau qis kub nyob rau hauv cov kev txwv hnyav (tshwj xeeb tshaj yog rau welded siv).
Lub corrosion kuj ntawm 2205 Duplex Stainless hlau
2205 stainless hlau 4 * 1mm capillary coiled tubing
- Uniform corrosion, corrosion kuj ntawm duplex stainless hlau 2205 yog superior rau 316L thiab 317L nyob rau hauv feem ntau ib puag ncig vim chromium ntsiab lus (22%), molybdenum (3%), thiab nitrogen cov ntsiab lus (0.18%).
Hauv zos los tiv thaiv corrosion, cov ntsiab lus ntawm chromium, molybdenum, thiab nitrogen hauv duplex stainless hlau 2205 ua rau nws tiv taus pitting thiab crevice corrosion hauv oxidizing thiab acidic daws. - Kev tiv thaiv kev ntxhov siab, Lub 2205 duplex qauv ntawm stainless hlau pab txhim kho cov kev tiv thaiv kev ntxhov siab corrosion tawg ntawm stainless hlau.Ntawm qhov kub thiab txias, nyob rau hauv cov xwm txheej ntawm nruj, oxygen, thiab chloride, chloride kev nyuaj siab corrosion tshwm sim hauv austenitic stainless hlau.Raws li cov xwm txheej no tsis yooj yim tswj tau, kev siv 304L, 316L, thiab 317L raug txwv rau qhov no.
- Anti-corrosion qaug zog, Dual-theem steel 2205 siab zog thiab corrosion kuj mus rau siab corrosion kuj qaug zog zog.Cov cuab yeej ua haujlwm tau raug cuam tshuam rau qhov chaw corrosive thiab thauj mus los, thiab cov khoom siv duplex stainless hlau 2205 yog qhov zoo rau cov ntawv thov.
Metallography txog Duplex Ss 2205 uns s31803
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm 2205 duplex steel muab qhov xav tau microstructure ntawm 50 ϫ / 50 tom qab 1900 / 1922 ° F (1040 ° C / 1080 ° C) cov kua tshuaj annealing.Yog tias qhov kev kho cua sov kub siab tshaj 2000 ° F, tej zaum yuav ua rau muaj kev nce hauv ferrite muaj pes tsawg leeg.Zoo li lwm yam duplex stainless hlau, 2205 alloys raug cuam tshuam rau cov theem dej nag.
Lub intermetallic theem precipitates ntawm 1300 ° F thiab 1800 ° F thiab precipitates ceev tshaj plaws ntawm 1600 ° F. Yog li ntawd, peb yuav tsum tau sim 2205, kom ntseeg tau tias tsis muaj intermetallic theem, kev xeem siv ASTM A 923.
