ASTM A790 S32750 SUPER DUPLEX Stainless Hlau Tshuaj Yeeb Nkab Yeeb Nkab
ASTM A790 $ 32750 yog qhov siab- tiv taus suplex cov raj, zoo tagnrho rau kev lag luam corrosive hauv kev lag luam tshuaj. Nws cov yam ntxwv tseem ceeb suav nrog cov ntsiab lus chromium siab, npib tsib, thiab molybdenum cov ntsiab lus corrosion thiab pitting, thiab kev sib xyaw ntawm Austenitic thiab Ferritic Microstructures. Qhov rai steel hlau no haum rau qhov ntsuas kub txog 600℃f, nrog tsawg kawg lub zog ntawm 550 mpa yam tsawg kawg ntawm 800 mpa (116,000 PSI).
Dab tsi yog ASTM A790 S32750 cov khoom siv?
ASTM A790 UNSIVE S32750 (Duplex 2507) Yog super duplex stainless hlau muaj 25% chromium, 4% molybdenum, thiab 7% npib tsib xee. Nws yog siv rau seamless thiab welded ferritic / austenitic stainless hlau yeeb nkab.
Tus txheej txheem no yog tus qauv txheem tshwj xeeb rau ferritic ustenitic stainless hlau leeg siv nyob rau hauv kev xeb ib puag ncig. ASTM A790 qhia txog cov ntsiab lus thiab cov kev xav tau rau kev tsim cov khoom siv tsis sib xws thiab cov hlua welded, thiab yuav tsum tau hais tias tsis muaj cov muab tub lim ntxiv rau thaum lub sij hawm vuam ntawm duplex thiab super duplex leeg.
Thaum twg tsim cov hlau tub rog siv Uns32203, S32750, S32750, thiab s32760, thiab s32520 cov ntaub ntawv sib tw yas yuav tsum tau ua raws li kev sib ntsib. ASTM A790 npog cov raj hlau ua kom deb li ntawm 1/8 nti (10.29 hli (762 hli) thiab phab ntsa thicknesses xws li 1.24 hli txog 12.7 hli. Raws li Ansi B36.10 Hlau Tube Standard, peb tuaj yeem muab cov hlau txiav hlau nrog lub diameters loj dua raws li A790 tus qauv.
Dab tsi yog ASTM A790 S32750 cov khoom siv?
S32750 yog super duplex stainless hlau stainless hlau, cov micrybdenum, tab sis nitrogen cov ntsiab lus, ua rau muaj zog ntxiv thiab muaj peev xwm ua tau zoo dua qub thiab muaj zog dua thiab kev ua kom zoo dua qub.
