S32750 Cov Hlau Stainless Seamless Tubing
Kev Taw Qhia Txog Khoom
Super Duplex stainless zoo li S32750, yog cov qauv sib xyaw ntawm austenite thiab ferrite (50/50) uas tau txhim kho lub zog dua li ferritic thiab austenitic steel qib. Qhov sib txawv tseem ceeb yog tias Super Duplex muaj cov ntsiab lus molybdenum thiab chromium siab dua uas muab cov khoom siv ntau dua. Cov chromium siab dua kuj txhawb nqa kev tsim cov theem intermetallic tsis zoo, uas rhiab heev rau 475 ° C embrittlement vim yog nag lossis daus ntawm chromium-nplua nuj α 'theem, thiab rau embrittlement los ntawm sigma, chi thiab lwm theem ntawm qhov kub siab dua.
Alloy 2507 (S32750) kuj muaj cov ntsiab lus nitrogen ntau dua, uas tsis yog tsuas yog txhawb nqa kev tsim cov austenite thiab ua rau lub zog nce ntxiv, tab sis kuj ncua qhov kev tsim cov theem intermetallic txaus kom tso cai rau kev ua thiab kev tsim cov qib duplex.
Qib no muaj cov tshuaj chloride zoo heev uas tiv taus xeb, ua ke nrog lub zog siab heev. Nws yog qhov tsim nyog rau kev siv rau hauv cov chaw muaj kev kub ntxhov xws li dej hiav txwv sov uas muaj chlorine thiab cov khoom siv uas muaj acidic chloride.
Cov yam ntxwv ntawm Alloy 2507 (S32750) yog raws li nram no:
● Kev tiv thaiv zoo heev rau kev tawg ntawm kev ntxhov siab (SCC) hauv cov chaw uas muaj chloride
● Zoo heev tiv taus xeb ntawm qhov tawg thiab qhov tawg
● Muaj zog tiv taus kev xeb dav dav
● Lub zog kho tshuab siab heev
● Cov khoom siv lub cev uas muaj txiaj ntsig zoo rau kev tsim qauv
● Muaj zog tiv taus kev xeb thiab kev qaug zog ntawm kev xeb
● Kev vuam zoo
S32750 yog tsim los rau cov ntawv thov uas xav tau lub zog tshwj xeeb thiab kev tiv thaiv corrosion, uas pom muaj nyob rau hauvcov txheej txheem tshuaj lom neeg, petrochemical, thiab cov khoom siv dej hiav txwv. Nws yog siv dav hauv kev tshawb nrhiav roj thiab roj av hauv hiav txwv thiab hauv cov khoom siv hloov pauv cua sov hauv kev ua petrochemical / tshuaj lom neeg. Qib no kuj tsim nyog rau kev siv hydraulic thiab cov cuab yeej siv hauv cov chaw nyob hauv hiav txwv sov.
