S32750 Stainless Hlau Seamless Tubing
Khoom Taw Qhia
Super Duplex stainless zoo li S32750, yog ib qho sib xyaw microstructure ntawm austenite thiab ferrite (50/50) uas tau txhim kho lub zog dua qib ferritic thiab austenitic steel. Qhov sib txawv tseem ceeb yog tias Super Duplex muaj ntau dua molybdenum thiab chromium cov ntsiab lus uas muab cov khoom siv ntau dua Cov chromium kuj txhawb kev tsim cov txheej txheem intermetallic, uas yog rhiab heev rau 475 ° C embrittlement vim nag lossis daus ntawm chromium-nplua nuj α' theem, thiab rau embrittlement los ntawm sigma, chi thiab lwm theem ntawm qhov kub thiab txias.
Alloy 2507 (S32750) kuj tseem muaj cov ntsiab lus nitrogen ntau dua, uas tsis tsuas yog txhawb kev tsim cov austenite thiab ua kom lub zog, tab sis kuj ncua kev tsim cov theem ntawm intermetallic txaus kom tso cai rau kev ua thiab tsim cov qib duplex.
Cov qib yog tus cwj pwm los ntawm cov tshuaj chloride corrosion zoo heev, ua ke nrog cov neeg kho tshuab siab heev. Nws yog tshwj xeeb tshaj yog haum rau kev siv nyob rau hauv ib puag ncig nruj xws li sov chlorinated seawater thiab acidic chloride-muaj xov xwm.
Alloy 2507 (S32750) cov yam ntxwv yog raws li nram no:
● Kev tiv thaiv zoo heev rau kev ntxhov siab corrosion cracking (SCC) nyob rau hauv ib puag ncig chloride-cov kabmob
● Zoo heev tiv taus pitting thiab crevice corrosion
● Siab tsis kam mus rau dav dav corrosion
● Cov neeg kho tshuab muaj zog heev
● Lub cev muaj zog uas muaj qhov zoo tsim
● Siab tiv thaiv corrosion corrosion thiab qaug zog corrosion
● Zoo weldability
S32750 yog tsim los rau kev thov cov ntawv thov uas yuav tsum tau tshwj xeeb lub zog thiab corrosion kuj, uas muaj nyob rau hauvtxheej txheem tshuaj, petrochemical, thiab seawater khoom. Nws yog dav siv nyob rau hauv offshore roj thiab roj kev tshawb nrhiav / ntau lawm thiab nyob rau hauv tshav kub exchangers nyob rau hauv petrochemical / tshuaj ua. Cov qib kuj tseem tsim nyog rau kev siv hydraulic thiab ntsuas kev siv nyob rau hauv qhov chaw sov sov marine.
