Gr12 Ti-0.3Mo-0.8Ni titanium ntawv
Tsim los ua UNS R53400, titanium qib 12 muaj cov npe ntawm Ti-0.3Mo-0.8Ni. Nws yog titanium alloy uas tej zaum yuav raug kho raws li unalloyed titanium (ua lag luam ntshiab titanium) nrog me kab ntawm alloying txheem.
Hauj lwm lawm
Qib 12 titanium sib xyaw ua haujlwm zoo thiab corrosion kuj tiv thaiv cov kab nrib pleb. Cov hlau no paub zoo rau nws qhov zoo weldability.
Titanium Qib 12 yog dab tsi?
Titanium Qib 12 0.8NI-0.3MO yog kev lag luam ntshiab wrought Titanium alloy. Qib 12 qhia tau hais tias muaj zog zoo ntawm qhov kub thiab txias, weldability zoo heev, thiab crevice corrosion kuj. Cov khoom no zoo ib yam li Titanium Qib 2 thiab Qib 3 nrog ntxiv ntawm molybdenum thiab npib tsib xee, uas muaj kev txhim kho corrosion kuj. Qib 12 tuaj yeem ua tau kub lossis txias tsim siv xovxwm nres txoj kev, hydropress forming, stretch forming los yog poob rauj txoj kev. Cov ntaub ntawv no muaj peev xwm tsim tau ntau txoj hauv kev ua rau Qib 12 muaj txiaj ntsig zoo hauv ntau daim ntawv thov.

FAQ
Dab tsi yog Titanium Qib 12?
A:Qib 12 titanium (UNS R53400) yog cov khoom lag luam ntshiab titanium derivative alloy uas muaj 0.3% molybdenum thiab 0.8% npib tsib xee. Nws yog tsim tshwj xeeb los txuas cov kev sib txawv ntawm cov qauv Qib 2 thiab palladium- cov qib siab zoo zoo li Qib 7. Nws muaj 40% lub zog siab dua li Qib 2, kev ua haujlwm siab tshaj qhov kub, thiab zoo dua corrosion kuj hauv kev txo cov acids thiab crevice tej yam kev mob - tag nrho ntawm tus nqi nruab nrab 5% ntawm 30–5%.
Dab tsi specifications npog Qib 12 titanium ntawv thiab phaj?
A:Lub ntsiab specifications yog:
ASTM B265 / ASME SB -265 - Daim ntawv, sawb, thiab phaj
ASTM B338 - Seamless thiab welded raj (condenser/heat exchanger)
ASTM B861 / B862 - Seamless thiab welded yeeb nkab
ISO 5832-11 - Daim ntawv thov kev kho mob (limited)
Qib 12 puas haum rau kev pabcuam flue gas desulfurization (FGD)?
A:Yog lawm. Qib 12 muaj cov ntaub ntawv zoo heev hauv FGD scrubbers, qhov hluav taws xob qhov hluav taws xob, thiab cov kab sib txuas. Nws muaj qhov ua tau zoo dua ntawm kev tiv thaiv corrosion dua li Qib 2 hauv acidic chloride condensates ntawm tus nqi qis dua qib 7.
Qib 12 Tsis haum rau qhov chaw nyob li cas?
A:
Concentrated reducing acids (>5% HCl, >10% H₂SO₄) - siv Qib 7, zirconium, lossis tantalum
Hydrofluoric acid (HF) - tawm tsam txhua qib titanium
fluoride-muaj cov xov xwm - txawm tias cov kab mob ua rau corrosion
Strongly oxidizing alkaline brines (>80 degree, siab pH, chlorides) - kev nyuaj siab corrosion cracking txaus ntshai
Nitric acid - Qib 12 ua haujlwm, tab sis Qib 2 zoo sib xws thiab pheej yig dua
Puas yog Qib 12 ASME Code pom zoo rau qhov kub siab?
A:Yog lawm. Qib 12 tau lees paub hauv ASME Tshooj VIII Division 1 thiab ASME B31.3 piping code nrog kev tso cai siab dua qib 2 ntawm txhua qhov kub. Qhov no tso cai rau cov phab ntsa nyias nyias thiab txuag cov khoom siv.
