254 SMO stainless hlau txhawb kev ua haujlwm tas li ntawm qhov kub txog li 540 degree; nws tuav nws cov tawv tawv ntawm qhov kub thiab txias yam tsis muaj kev hloov pauv, ua rau nws haum rau ntau yam kev ua haujlwm ntawm -40℃txog 540℃. Nws nthuav tawm ib qho kev poob qis hauv lub zog raws li qhov kub thiab txias thiab muaj kev tiv thaiv zoo tshaj qhov kub thiab txias piv rau cov qauv austenitic stainless hlau.
254 SMO muaj lub zog siv tshuab siab heev- nrog lub zog tawm los ntawm 1.8 npaug ntawm 316L (170 MPa)- tso cai rau nws tiv taus cov kav dej ntau dua thiab cov khoom siv thauj khoom. Nws yog qhov zoo - haum rau siab - cov tshuaj tiv thaiv siab thiab siab - cov ntawv thov kev thauj mus los, muab kev tiv thaiv zoo rau deformation thiab cuam tshuam.

Cov qhab nia xaiv tau
- Rau cov txheej txheem kev siv tshuaj lom neeg uas muaj kev xeb me me-xws li kev thauj mus los ntawm ambient-kub dej tshiab lossis tsis muaj zog acids thiab alkalis-316L stainless hlau yog qhov kev xaiv tsim nyog, muab cov nqi qis dua 254 SMO.
- 904L muaj PREN tus nqi ntawm 32-35; nws cov corrosion kuj nyob rau hauv siab -chloride ib puag ncig yog ho qis dua li ntawm 254 SMO, ua rau nws haum rau tshuaj tej yaam num uas txwv tsis pub siv nyiaj uas tsis tas yuav ua hauj lwm rau siab -chloride corrosion.
- AL-6XN super austenitic stainless hlau muaj kev ua tau zoo piv rau 254 SMO, nrog PREN tus nqi kwv yees li 45 thiab me ntsis superior corrosion kuj; thaum nws tsim nyog rau qhov hnyav heev, siab -chloride ib puag ncig, nws cov nqi yuav khoom ntau dua ua rau tus nqi qis dua piv rau 254 SMO.
thaj chaw thov
ASTM A312 254 SMO stainless hlau nta Pitting Resistance Equivalent Number (PREN) ntawm 42–45, nrog rau kev ua haujlwm zoo heev rau kev xeb hauv zos, muaj zog txhua yam, thiab weldability zoo. Nws yog feem ntau siv hauv kev lag luam chemical ua rau cov ntawv hauv qab no:

FAQ
Q: Puas tuaj yeem 254 SMO hloov 904L hauv acidic tshuaj ua haujlwm ib puag ncig?
A: Yog. 254 SMO tsis tsuas yog khaws cia 904L qhov kev tiv thaiv zoo heev rau cov organic thiab txo cov kua qaub, tab sis nws cov ntsiab lus molybdenum siab kuj tseem ua rau nws muaj zog tiv thaiv chloride corrosion thiab kub kub piv rau 904L, ua rau nws tsim nyog rau cov cheeb tsam sib xyaw nrog cov kua qaub thiab alkalis lossis acidic media uas muaj chlorides.
Q: Puas yog 254 SMO seamless yeeb nkab haum rau siab -chloride chemical media xws li seawater thiab brine?
A: 254 SMO muaj qhov tseem ceeb pitting kub ntawm ntau dua lossis sib npaug li 50℃thiab qhov tshwj xeeb tshaj yog PREN tus nqi, tso cai rau nws tiv taus corrosive, siab -chloride media-xws li dej hiav txwv, concentrated brine, thiab siab - dej qab ntsev - lub sij hawm ntev; nws yog tsim rau kev siv xws li seawater desalination thiab tshuaj brine ncig tshuab.
Q: Dab tsi yog qhov vuam yam ntxwv ntawm 254 SMO? Puas yog tom qab-weld kev kho cua sov xav tau?
A: Nws muaj qhov zoo tshaj plaws weldability, thiab tom qab - vuam kev kho cua sov feem ntau tsis tas yuav tsum tau; Txawm li cas los xij, nyob rau hauv ib puag ncig corrosive heev, post-weld pickling thiab passivation raug pom zoo kom rov ua kom corrosion.
