4. 254 SMO Description:

a. 254SMO yog austenitic stainless hlau. Vim nws cov ntsiab lus molybdenum siab, nws muaj qhov tsis kam tiv thaiv corrosion

thiab crevice corrosion.

b. Hom stainless hlau no yog tsim los siv rau hauv ib puag ncig uas muaj halides xws li dej hiav txwv. 254SMO kuj muaj qhov zoo

tsis kam mus rau uniform corrosion.

c. Tshwj xeeb tshaj yog nyob rau hauv cov kua qaub uas muaj halide, cov hlau yog superior rau zoo tib yam stainless hlau. Nws cov ntsiab lus C yog <0.03%, yog li nws hu ua

ntshiab austenitic stainless hlau (<0.01% tseem hu ua super austenitic stainless hlau). Super stainless hlau yog ib hom tshwj xeeb stainless hlau.

d. Ua ntej ntawm tag nrho cov, nws yog txawv los ntawm zoo tib yam stainless hlau nyob rau hauv tshuaj muaj pes tsawg leeg. Nws yog hais txog ib hom high alloy stainless hlau

muaj cov nickel siab, siab chromium thiab molybdenum siab. Qhov nrov tshaj plaws yog 254SMo uas muaj 6% Mo. Cov hlau no

muaj zoo heev hauv zos corrosion kuj.

e. Nws muaj qhov zoo pitting corrosion kuj (PI ≥ 40) thiab kev ntxhov siab corrosion nyob rau hauv cov dej hiav txwv, aeration, crevice

thiab low-speed scouring.

f. Nws yog cov khoom siv hloov pauv rau Ni puag alloy thiab titanium alloy. Thib ob, nyob rau hauv cov nqe lus ntawm kub tsis kam los yog corrosion kuj,

nws muaj zoo heev kub kub kuj los yog corrosion kuj, uas yog irreplaceable rau 304 stainless hlau. Ntxiv rau,

los ntawm kev faib tawm ntawm cov hlau tsis muaj steel, cov qauv metallographic ntawm cov hlau stainless tshwj xeeb yog cov qauv austenitic metallographic ruaj khov.

g. Raws li qhov tshwj xeeb stainless hlau no yog cov khoom siv alloy siab, nws cov txheej txheem tsim khoom yog qhov nyuaj heev. Feem ntau, tib neeg tuaj yeem tso siab rau

cov txheej txheem ib txwm ua los tsim cov hlau tsis huv tshwj xeeb no, xws li nchuav, forging, dov, thiab lwm yam.

5. Daim ntawv thov:

1) Dej hiav txwv: marine qauv ntawm marine ib puag ncig, seawater desalination, mariculture, seawater heat exchange, thiab lwm yam.

2) Kev tiv thaiv ib puag ncig: flue gas desulfurization ntaus ntawv rau thermal zog tsim, kev kho dej khib nyiab, thiab lwm yam.

3) Lub zog: kev tsim hluav taws xob atomic, kev siv cov thee, kev tsim hluav taws xob tidal, thiab lwm yam.

4) Petrochemical kev lag luam: roj refining, chemical khoom, thiab lwm yam.

5) Khoom noj khoom haus: ntsev ua, kua ntses brewing, thiab lwm yam.

6) High concentration chloride ib puag ncig: ntawv kev lag luam, ntau yam khoom siv tshuaj dawb.

6. Kev kho mob ntxiv:

1) Polish
