Titanium Qib 5 vs Qib 2 Titanium
Jan 15, 2026
Ti 6Al-4V yog qhov siv dav tshaj plaws ntawm txhua qib Titanium. Nws yog feem ntau muaj nyob rau hauv cov mob annealed thiab yog yooj yim kho cua sov kom muaj zog, rau ntau yam kev siv. Raws li lub hom phiaj dav dav, Ti 6Al-4V muaj qhov dav dav ntawm cov khoom tsim nyog ntawm qhov kub ntawm -210 ° C - 400 ° C.
Titanium qib 5 lossis Ti 6Al-4V yog alpha-beta (α-β) alloy. Yog li, nws yuav raug kho kom sov kom muab qhov nruab nrab- lub zog siab hauv cov ntu hauv qab 100 hli tuab. Txawm li cas los xij, hardenability yog txwv thiab cov seem tshaj 25 hli yuav tsis ua tiav cov khoom xav tau. Ti 6Al-4V muaj qhov zoo weldability (nrog txuam lossis ELI muab tub lim) thiab kub-formability. Txawm li cas los xij, qhov℃ntawm qhov txias txias yog txwv.
Titanium qib 1 yog qhov zoo tshaj plaws ntawm cov khoom lag luam ntshiab titanium qib. Yog li ntawd, lub alloy yog dav teev rau kev tsim cov phaj kub exchangers.
Titanium Qib 2 lossis Titanium CP3 yog cov khoom lag luam ntshiab alpha (α) alloy. Txawm hais tias tsis muaj zog li Ti 6Al-4V, Titanium qib 2 muaj qhov zoo tshaj plaws corrosion tiv thaiv ntau yam kev tawm tsam. Piv txwv li, Titanium qib 2 zoo tiv thaiv cov tshuaj chlorine ntub dej ntawm 10 ° C - 80 ° C (0-0.02 mpy lossis 0.001 mm / y) thiab yog li, siv los ua cov tshuaj chlorine dioxide mixers, pipework thiab fasteners nyob rau hauv niaj hnub bleach nroj tsuag.
Titanium qib 2 tau teev tseg raws li nws cov kev tiv thaiv zoo heev nyob rau hauv ib puag ncig uas suav nrog: calcium chloride, cupric chloride, ferric chloride, ntau cov ntsiab lus ntawm acetic acid, kub dej hiav txwv, feem ntau cov organic media thiab ntau dua.
Txawm li cas los xij, lwm yam kev mob xws li qhov kub thiab txias, qib pH thiab qhov nrawm nrawm tuaj yeem hloov kho nws cov khoom muaj zog xws li cuam tshuam rau kev ntxhov siab corrosion tawg thiab crevice corrosion. Thaum piv nrog Titanium qib 5 (Ti 6Al-4V), Titanium qib 2 feem ntau xaiv qhov twg aqueous corrosion kuj thiab / los yog formability yuav tsum tau.
| Cov khoom | Ti 6Al-4V (UNS R56400) | Titanium Qib 2 (UNS R50400) |
|---|---|---|
| metallurgy | 895mpa ua | 345 MPa rau |
| Qhov kawg tensile zog | 827mpa ua | 276 MPa ua |
| 0.2% offset yield zog | 827mpa ua | 276 MPa ua |
| % Elongation (Ductility) | 10 | 20 |
| Corrosion kuj | Zoo heev | Zoo heev |
| Creep thiab stress-rupture | Siab | NA |
| Kev qaug zog | Siab | NA |
| Kev pabcuam kub | -210 ° C - 400 ° C rau kev txhim khu kev qha zoo | Nyob ntawm ib puag ncig xws li mus txog 316 ° C rau chav dej thiab dej hiav txwv |
| Weldability | Weldable |
Thaum kub txog li 200 ° C nyob rau hauv ib txwm huab cua, Titanium qib 2 thiab lwm cov qib ntshiab coj mus muag kuj yog ib qho kev xaiv nrov rau cov khoom siv hauv ob sab phlu, thaum xav tau kev tiv thaiv corrosion ntawm qhov chaw. Feem ntau pheej yig dua thiab muaj zog steels yog siv los ua cov rooj sib txoos sab nrauv. Ib daim ntawv thov tseem ceeb yog hauv ob sab phlu ntawm cov kab hluav taws xob ntawm cov hluav taws xob hluav taws xob hluav taws xob uas tau hloov kho nrog FGD Systems (Flue Gas Desulphurisation plant).
