Cov lus nug nquag
Q: Cov txiaj ntsig tseem ceeb ntawm 50: 50 duplex theem tshuav yog dab tsi?
A: Qhov sib npaug microstructure sib xyaw ua ke lub siab txhua yam lub zog ntawm ferrite nrog rau qhov zoo heev corrosion kuj ntawm austenite. Qhov no ua rau ob zaug lub zog tawm los ntawm cov qauv stainless hlau thiab tshwj xeeb tsis kam rau kev ntxhov siab corrosion cracking.
Q: Cov kav dej super duplex seamless puas tuaj yeem siv rau hauv qhov chaw siab -salinity?
A: Yes. Super duplex grades such as UNS S32750 and S32760 contain elevated levels of chromium, molybdenum, and nitrogen. Achieving a PREN >= 40, lawv tau tsim tshwj xeeb rau cov dej hiav txwv sov thiab siab -chloride daim ntaub ntawv.
Q: Cov ntaub ntawv dab tsi yog muab los lav cov khoom tseeb?
A: Tag nrho cov khoom xa tuaj suav nrog EN 10204 3.1 lossis 3.2 Cov Khoom Siv Xeem Ntawv Pov Thawj (MTC) piav qhia txog cov xov tooj cua sov tshwj xeeb, tshuaj ntsuam xyuas cov tshuaj lom neeg, cov txiaj ntsig kev ntsuas tshuab, suav ferrite, thiab tsis yog - cov ntawv ceeb toom kev puas tsuaj.
Q: Puas yog qhov kev cai loj, qhov ntev, thiab kev zam tshwj xeeb muaj rau qhov kev txiav txim?
A: Yog. Cov sij hawm tsim khoom ua kom haum raws li qhov loj me me, cov phab ntsa tshwj xeeb, ruaj - txiav qhov ntev, thiab nruj geometric kam rau ua kom haum rau qhov tseeb engineering specifications.
