Ibyiza by'ingenzi bya Duplex F50

Imbaraga nyinshi– Duplex F50 itanga imbaraga zo gutanga umusaruro zingana na 450 MPa (65 ksi), hafi inshuro ebyiri z’icyuma kitagira umugozi cya 316L (220 MPa). Ubu bunini butuma abashushanya bashobora kugena ibice by’inkuta bito cyane, bigabanyiriza uburemere rusange n’ikiguzi cy’ibikoresho mu miterere n’ikoreshwa ry’umuvuduko. Kongeraho azote bitanga imbaraga zo kongera ubushobozi bwo gukora neza hatabayeho kwangiza ubushobozi bwo gukora.

Ubudahangarwa Bwiza bwo Kurwanya Ingese– Duplex F50 ifite agaciro ka 34-36, itanga ubushobozi bwo kurwanya ingese n’ibiturika mu duce turimo chloride iri hagati. Ingano ya chromium nyinshi (26-29%) ituma habaho firime idahindagurika, mu gihe molybdenum (1.0-2.5%) yongera ubushobozi bwo kurwanya ingese. Ibi bituma F50 ikoreshwa mu miyoboro y’amazi yo mu nyanja, gutunganya imiti, no gukoresha mu mazi aho 316L idahagije ariko ingano ya Super Duplex ishobora kuba irenze urugero.

Kongera azote– Ingano ya azote (0.15-0.35%) itanga inyungu nyinshi: kongera imbaraga mu gupima ibintu bikomeye kugira ngo umusaruro urusheho kwiyongera; kunoza ubukomere no kudahindagurika; kongera ubudahangarwa ku icupa ry’amazi; no gukomeza uburyo bwa austenite kugira ngo urusheho gusudira neza. Azote ni ikintu cy’ingenzi mu miterere ya none y’icyuma kitagira umugese cya duplex.

Ubudahangarwa bwiza bwo kwangirika kw'imitsi ya Chloride– Imiterere mito ya ferritic-austenitic itanga ubudahangarwa bukomeye bwo kwangirika kwa chloride stress corrosion (SCC), uburyo busanzwe bwo kwangirika ku byuma 304 na 316 bita stainless steel mu bidukikije byo mu mazi no mu binyabutabire. Imiterere mito ivanze irinda ko imyanda yangirika vuba cyane.

Ubushuti bwiza– Duplex F50 ishobora gusudira hakoreshejwe uburyo busanzwe burimo GTAW (TIG), GMAW (MIG), SMAW (stick), na SAW (submerged arc). Guhuza icyuma gifunga (ubusanzwe ER2209 cyangwa ikindi gisa nayo) birasabwa. Gucunga neza uburyo ubushyuhe bwinjira (ubusanzwe 0.5-2.5 kJ/mm) no gucunga ubushyuhe hagati y’ibice (≤ 150°C) ni ingenzi kugira ngo hagumane ferrite-austenite ingana neza (ubusanzwe 40-60% ferrite) mu gace kasudira n’agace kagizweho ingaruka n’ubushyuhe.

Uburyo bwo kugabanya ikiguzi– Duplex F50 itanga uburinganire bwiza mu mikorere n'igiciro, itanga ubudahangarwa bwo kwangirika hafi ya Duplex 2205 ku giciro gito. Ibi bituma iba amahitamo meza ku bikorwa aho imikorere yo hejuru ya 2205 idakenewe, cyangwa aho ibiciro bigabanuka cyane.

Ubuhanga bwiza bwo gukora– Ifu irashobora gukorwa byoroshye, igakorwa hakoreshejwe imashini, kandi igakorwa hakoreshejwe uburyo busanzwe. Ifite ubushobozi bwo gukora neza bushyushye n'ubukonje, nubwo imbaraga zayo nyinshi zisaba ibikoresho bikomeye byo kuyitunganya no kuyikata ugereranije n'uburyo bwo kuyitunganya.

Ibibazo Bikunze Kubazwa

Q: Ni irihe tandukaniro riri hagati ya Duplex F50 na Duplex 2205?

A: Duplex F50 ifite chromium nyinshi (26-29% vs 22-23%) ariko molybdenum nke (1.0-2.5% vs 3.0-3.5%). Ibi bitanga agaciro ka PREN gasa (34-36 vs ≥36) ariko ku giciro gito. Duplex 2205 itanga ubushobozi bwo kurwanya imyanda neza gato bitewe na molybdenum nyinshi, mu gihe F50 itanga chromium nyinshi kugira ngo irusheho kurwanya oxidation. F50 ihendutse kandi ikunze gutorwa mu bikorwa aho igiciro cya 2205 kidafite ishingiro.

Q: Ese Duplex F50 ikwiriye gukoreshwa mu mazi yo mu nyanja?

A: Yego, ku bijyanye no gukoresha amazi yo mu nyanja mu buryo buri ku rugero. PREN ya 34-36 itanga ubushobozi bwo kurwanya imyobo mu mazi yo mu nyanja, bigatuma ikoreshwa mu bikorwa byinshi byo mu mazi yo mu nyanja. Ku mazi yo mu nyanja afite ubushyuhe bwinshi, amazi yo mu nyanja adatemba, cyangwa chloride ikomeye cyane, Super Duplex 2507 (PREN ≥ 40) ishobora gukenerwa.

Q: Ese Duplex F50 ishobora gusudira byoroshye?

A: Yego. Duplex F50 ishobora gusudira hakoreshejwe uburyo bwa GTAW (TIG), GMAW (MIG), SMAW (stick), na SAW (submerged arc). Guhitamo ibyuma byuzuza bigomba guhuza na shimi y'ibikoresho by'ibanze. Kugenzura neza ubushyuhe (0.5-2.5 kJ/mm) no gucunga ubushyuhe hagati y'ibice (≤150°C) ni ingenzi kugira ngo habeho uburinganire bukwiye hagati ya ferrite na austenite no kurwanya ingese mu gace k'ubushyuhe.

Q: Ni ubushyuhe ntarengwa bwa serivisi ya Duplex F50 ni ubuhe?

A: Ubushyuhe ntarengwa busabwa ni 300°C (572°F). Hejuru y'ubu bushyuhe, ifu irashobora kwangirika bitewe n'imvura ya sigma phase. Ubushyuhe ntarengwa bushobora kuba hafi -50°C.

Q: Agaciro ka PREN ka Duplex F50 ni akahe?

A: PREN (Umubare uhwanye n'umuvuduko w'ubudahangarwa) wa Duplex F50 ni hafi 34-36, ubarwa hakoreshejwe formula: PREN = %Cr + 3.3×%Mo + 16×%N.

Q: Ni iki gikoreshwa mu Bushinwa cya Duplex F50?

A: Igipimo cy'Abashinwa kingana na 022Cr26Ni5Mo2N (GB/T 20878). Nanone gikunze kuvugwa mu izina rya UNS S32950 na F inomero F50.

Q: Ni izihe fomu z'ibicuruzwa biboneka kuri Duplex F50?

A: Womic Steel itanga Duplex F50 mu muyoboro udafite umugozi, umuyoboro ushongeshejwe, icyuma gifunganye, isahani y'icyuma, icyuma gifunganye, umugozi, flanges, imiyoboro, forgings, na valves. Ibisobanuro byuzuye by'ibicuruzwa n'ingano byanditse mu gice cy'ibicuruzwa biboneka.
