S32750 Ibyuma bitagira umuyonga

Ibisobanuro bigufi:

Alloy 2507, hamwe na UNS numero S32750, ni ibice bibiri bivanze bishingiye kuri sisitemu ya fer-chromium-nikel hamwe nuburyo buvanze bingana na austenite na ferrite. Bitewe nuburinganire bwa duplex, Alloy 2507 irerekana uburyo bwiza bwo kurwanya ruswa muri rusange nkiyuma ya austenitike idafite ibyuma hamwe nibintu bisa. Byongeye kandi, ifite imbaraga nyinshi kandi zitanga umusaruro kimwe na chloride SCC irwanya cyane ugereranije na bagenzi bayo ba austenitike mugihe ikomeza ingaruka zikomeye kurenza bagenzi ba ferritic.

Kumenyekanisha ibicuruzwa

Super Duplex idafite umwanda nka S32750, ni microstructure ivanze ya austenite na ferrite (50/50) yazamuye imbaraga hejuru yicyuma cya ferritic na austenitis. Itandukaniro nyamukuru nuko Super Duplex ifite molybdenum nyinshi hamwe na chromium itanga ibikoresho binini Chromium yo hejuru nayo iteza imbere gushiraho ibyiciro byangiza intermetallic, byunvikana no kwinjiza 475 ° C kubera imvura igwa kuri chromium ikungahaye α ', no gushira hamwe na sigma, chi nibindi byiciro mubushyuhe bwo hejuru.

Alloy 2507 (S32750) nayo ifite azote nyinshi, ntabwo iteza imbere ishingwa rya austenite kandi ikongerera imbaraga, ahubwo ikanadindiza ishyirwaho ryibyiciro bya intermetallic bihagije kugirango yemererwe gutunganya no guhimba urwego rwa duplex.

Urwego rurangwa na chloride nziza cyane yo kurwanya ruswa, ihujwe nimbaraga zo hejuru cyane. Birakwiriye cyane cyane gukoreshwa mubidukikije bikaze nkamazi yo mu nyanja ashyushye ya chlorine hamwe nibitangazamakuru birimo chloride.

Alloy 2507 (S32750) ibiranga nibi bikurikira:

Resistance Kurwanya bihebuje kunanirwa kwangirika (SCC) mubidukikije byitwa chloride
Resistance Kurwanya bihebuje guhangana no gutobora
Kurwanya cyane ruswa
Imbaraga zikomeye cyane
Properties Imiterere yumubiri itanga ibyiza byo gushushanya
Kurwanya cyane isuri kwangirika no kunanirwa
Eld Weldability nziza

S32750 yagenewe gusaba porogaramu zisaba imbaraga zidasanzwe no kurwanya ruswa, ziboneka muriuburyo bwa shimi, ibikomoka kuri peteroli, n'ibikoresho byo mu nyanja. Ikoreshwa cyane mubushakashatsi bwa peteroli na gazi yo hanze / kubyara no guhanahana ubushyuhe mubikorwa bya peteroli / imiti. Urwego narwo rukwiranye na hydraulic nibikoresho bikoreshwa mubidukikije byo mu turere dushyuha.
