Ibyiza by'ingenzi bya Duplex 31803

Imbaraga nyinshi– Duplex 31803 itanga imbaraga zikubye kabiri icyuma kitagira umugese cya 316L, bigatuma abashushanya bashobora gushyiraho ibice by'inkuta bito kandi bakagabanya uburemere muri rusange. Izi mbaraga nyinshi zigerwaho binyuze mu miterere ya ferritic-austenitic, ihuza imbaraga za ferrite n'ubushobozi bwo gupfunyika no gukomera kwa austenite.

Ubudahangarwa bw'inkongi– Iyi aluminiyumu itanga ubudahangarwa bwiza ku myobo n'ingufu mu bidukikije birimo koloride. Agaciro ka PREN kangana na 34 gatanga imikorere myiza mu mazi yo mu nyanja n'imiti biri ku rugero rwo hagati.

Ubudahangarwa ku kwangirika kw'umuvuduko w'ingufu– Duplex 31803 itanga ubushobozi bwo kurwanya corrosion cracking (SCC), uburyo bwo gucika intege busanzwe ku byuma bitagira umugese bya austenitic mu duce twa chloride. Icyiciro cya ferrite gitanga ubushobozi bwo kurwanya SCC buruta 304 na 316.

Ubushuhe– Ifu irashobora gusudira hakoreshejwe uburyo busanzwe bwo gusudira hakoreshejwe ibyuma bikwiye. Gucunga neza uburyo bwo gushyushya no gucunga ubushyuhe hagati y’ibice birakenewe kugira ngo ferrite na austenite bigumane uburinganire bukwiye mu gace ko gusudira.

Ihendutse ku giciro– Duplex 31803 itanga uburyo buhendutse bwo gusimbura aloyi za nikeli n'ibyuma bya duplex byo mu rwego rwo hejuru, itanga uburinganire bwiza mu mikorere n'igiciro ku bikorwa bitandukanye.

Ibibazo Bikunze Kubazwa

Q: Ni irihe tandukaniro riri hagati ya Duplex 31803 na Duplex 2205?

A: Duplex 2205 (S32205) ifite uburyo bwo kugenzura cyane molybdenum (3.0-3.5%) na azote (0.14-0.20%), itanga ubushobozi bwo kurwanya ingese (PREN 36 vs 34) kandi ni yo ikoreshwa cyane mu mazi no mu nyanja.

Q: Ese Duplex 31803 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 itanga ubushobozi bwo kurwanya imyobo mu mazi yo mu nyanja, bigatuma ikoreshwa mu bikorwa byinshi byo mu mazi yo mu nyanja. Ku bijyanye n'amazi yo mu nyanja akomeye cyane, Super Duplex 2507 (PREN ≥ 40) ishobora kuba ngombwa.

Q: Ese Duplex 31803 ishobora gusudira byoroshye?

A: Yego, hamwe n'uburyo bwo gusudira bukwiye. Ifu irashobora gusudira byoroshye hakoreshejwe uburyo bwa GTAW, GMAW, na SMAW. Kugenzura uburyo ubushyuhe bwinjira n'ubushyuhe bwo hagati ni ingenzi kugira ngo habeho uburinganire bukwiye hagati ya ferrite na austenite.
