SAF2205 ni iki?

SAF2205 ni ubwoko bwa kera bw'icyuma kitagira umugese cyakozwe na Sandvik, bivuze Sandvik Austenite Ferrite. Izwiho gukomera kwayo no kurwanya kwangirika kwa chloride, kandi ifatwa nk'ikintu gifasha mu kurwanya kwangirika kw'icyuma gikingiraikibaya cy'amaziIbikoresho byo kuvugurura ibyuma bisanzwe bitagira umugese nka 316L bikajya mu byuma bitagira umugese bitagira umugese. Ubwiza bwayo buri mu miterere yayo y'imbere, iri hafi kimwe cya kabiri cya ferrite n'igice cya austenite, bihuza ibyiza by'imiterere mito yombi.

Imikorere ya SAF2205 ishobora kugereranywa neza n'icyitegererezo gisanzwe gikoreshwa cya 316L ku buryo bukurikira:

• Imbaraga:Hafi 450 MPa, bingana na kabiri y’ubunini bwa 316L, bigatuma inkuta zirushaho kuba nto.
• Ubudahangarwa bw'inkongi (agaciro ka PRE):≥35, hejuru cyane ya 316L ya 24. Ifite ubudahangarwa bukomeye cyane ku myobo n'imyenge mu bidukikije birimo chloride (nk'amazi yo mu nyanja).
• Gucika kw'ingufu:Ni byiza cyane. Mu bidukikije birimo chloride, 316L ikunze kwangirika iyo ubushyuhe buri hejuru ya 60°C, mu gihe SAF2205 ifite ubushobozi bwo guhangana n’ibiyiko.

SAF2205 ifite amazina menshi asanzwe y’impanga. Nyamuneka witondere itandukaniro riri hagati y’ibicuruzwa mu gihe ugura:

• UNS S31803:Icyiciro cya mbere.
• UNS S32205:Ni igipimo kigezweho kandi gikoreshwa cyane gifite uburyo bwo kugenzura cyane imiterere (cyane cyane azote), kandi gifite ubushobozi bwo kurwanya ingese kurusha S31803 yo mu rwego rwa kera.
• EN 1.4462:Icyitonderwa gishingiye ku gipimo cya EU.

Hamwe n'uruvange rwa"Imbaraga nyinshi + kurwanya ingese", ikunze gukoreshwa mu gusimbuza 316L kugira ngo ihangane n'imimerere ikomeye y'akazi:

• Inganda zikora peteroli n'ibinyabutabire:imiyoboro y'ubushyuhe, imiyoboro, imiyoboro y'umuvuduko, cyane cyane ikwiriye ahantu harimo iyoni za kloride na sulfide ya hydrogen.
• Ubwubatsi bw'ubwato:Ibikoresho byo gukuramo umunyu mu mazi yo mu nyanja, ibice by'ubwubatsi bw'ubwato, birwanya ingese mu mazi yo mu nyanja.
• Inganda zikora impapuro n'imiti:inkono zo gutekeshamo, ibikoresho byo gusiga ibara ry'umuhondo, ibikoresho bya PTA (aside terephtalike purified), nibindi.
• Ibintu byihariye:ishobora kandi gukoreshwa mu gukora amasoko y'amazi akora neza cyane (-100 kugeza kuri 300℃ birakenewe) cyangwa ibikoresho by'amenyo.
