Ibisobanuro by'igicuruzwa
Super Duplex 2507 ni yo irusha izindi zose mu muryango w’icyuma gishyuha cya duplex, itanga imbaraga zo gutanga umusaruro zikubye kabiri ugereranyije n’icyuma gishyuha cya 316L (550 MPa vs 220 MPa) mu gihe itanga imbaraga zo kurwanya ingese nk’uko bimeze kuri aloyi za nikeli ku giciro gito cyane. Ifite chromium nyinshi (24-26%), molybdenum (3-5%), na azote (0.24-0.32%), Super Duplex 2507 igera kuri PREN ≥ 40, ikora neza mu mazi yo mu nyanja na chloride. Iyi aloyi iboneka kandi nka UNS S32760 (F55) hamwe n’umuringa na tungsten byongerewemo imbaraga zo kurwanya ingese.
Ibintu by'ingenzi biranga umuntu birimo:

Ibyiza by'ingenzi bya Super Duplex 2507
Ubudahangarwa budasanzwe bwo kwangirika– Super Duplex 2507 itanga ubushobozi bwo kurwanya ingese mu byuma bitagira ingano bibiri. Ifite PREN ≥ 40, iyi alloy itanga ubushobozi bwo kurwanya ingese, ingese zicika, ndetse n’ingese zicika mu duce twa chloride irimo amazi yo mu nyanja, amazi y’umunyu n’amazi y’umunyu, ndetse n’ibisubizo bya aside chloride.
Ingufu nyinshi cyane mu byuma bibiri– Super Duplex 2507 itanga imbaraga nyinshi kurusha icyuma cyose kitagira umugese cya duplex, ifite imbaraga nkeya za 550 MPa. Ibi bituma abashushanya bashobora kugena ibice by'inkuta bito cyane, bigabanyiriza uburemere n'ikiguzi cy'ibikoresho mu bikorwa by'ingenzi.
Ubudahangarwa bwo kwangirika kw'ingufu mu gihe cy'ubushyuhe bwa Chloride– Imiterere mito ya ferritic-austenitic itanga ubudahangarwa bukomeye bwo kwangirika kwa chloride stress corrosion (SCC), bigatuma Super Duplex 2507 ikwiriye ibidukikije byo mu nyanja no mu nyanja aho SCC ari ikibazo gikomeye.
Imikorere myiza cyane yo mu mazi yo mu nyanja– Super Duplex 2507 ni kimwe mu bikoresho bike bikwiriye gukoreshwa mu gihe kirekire mu mazi yo mu nyanja nta kwangirika. PREN yayo ≥ 40 ituma amazi yo mu nyanja adashobora kwangirika bitewe n’imyobo n’imisatsi, bigatuma iba ibikoresho bikundwa cyane mu bikoresho byo munsi y’inyanja no mu nkombe z’inyanja.
Ubushuti bwiza– Super Duplex 2507 ishobora gusudira hakoreshejwe uburyo busanzwe (GTAW, GMAW, SMAW, SAW) hakoreshejwe ibyuma bikwiye (ubusanzwe ER2594 cyangwa ER2507). Kugenzura neza ubushyuhe no gucunga ubushyuhe hagati y’ibice ni ingenzi kugira ngo habeho kuringaniza neza ferrite na austenite no kurwanya ingese mu gace kasudira.
Iyubahirizwa rya NACE MR0175 / ISO 15156– Super Duplex 2507 yujuje ibisabwa kugira ngo ikoreshwe mu nganda za peteroli na gaze, irwanya gucika kwa sulfide stress (SSC) no gucika kwa hydrogen induced (HIC) mu bidukikije birimo H₂S.
Uburyo bwo kugabanya ikiguzi– Super Duplex 2507 itanga ubushobozi bwo kurwanya ingese nk'uko bimeze kuri aloyi za nikeli nka Inconel 625 ku giciro gito cyane, bigatuma iba ubundi buryo bwiza bwo gukoresha ibintu byinshi.
Iyubahirizwa rya NORSOK M-630– Iyi aloyi yujuje ibisabwa na NORSOK M-630 mu bikorwa byo mu mazi, bigatuma ikoreshwa mu mishinga yo gusiga ibikoresho ku mugabane wa Noruveje.
