Alloy 317L (UNS S31703) nicyuma cyitwa molybdenum gifite ibyuma bya austenitike bitagira umuyonga hamwe no kongera imbaraga zo kurwanya ibitero byimiti ugereranije na chromium-nikel austenitike isanzwe idafite ibyuma nka Alloy 304. Byongeye kandi, Alloy 317L itanga umuvuduko mwinshi, guhangayika-kuri- guturika, n'imbaraga zikaze ku bushyuhe bwo hejuru kuruta ibyuma bisanzwe bidafite ingese.Ni karubone nkeya cyangwa "L" itanga imbaraga zo kurwanya ubukangurambaga mugihe cyo gusudira hamwe nubundi buryo bwo gutwika.
317 / 317L ibyuma bitarimo ibyuma
Kurwanya ruswa
Ibirungo byinshi bya molybdenum biri muri Alloy 317L byizeza ko rushobora kurwanya ruswa muri rusange kandi ikaboneka mu bitangazamakuru byinshi iyo ugereranije na 304 / 304L na 316 / 316L ibyuma bitagira umwanda.Ibidukikije bidatera 304 / 304L ibyuma bitagira umwanda mubisanzwe ntibishobora kwangirika 317L.Ikintu kimwe kidasanzwe, ariko, ni okiside cyane acide nka acide nitric.Amavuta arimo molybdenum muri rusange ntabwo akora neza muribi bidukikije.
317 / 317L ibyuma bitarimo ibyuma
Alloy 317L ifite ruswa nziza yo kurwanya ruswa yimiti myinshi.Irwanya kwibasirwa na acide sulfurike, chlorine acide na aside fosifori.Ikoreshwa mugukoresha acide organic organique na fatty acide ikunze kuboneka mubiribwa no gutunganya imiti.
317 / 317L ibyuma bitarimo ibyuma
Kurwanya ruswa ya 317 na 317L bigomba kuba bimwe mubidukikije runaka.Kimwe kidasanzwe ni aho ibivange bizagerwaho nubushyuhe bwa chromium karbide yimvura ya 800 - 1500 ° F (427 - 816 ° C).Kubera karuboni nkeya, 317L nibikoresho byatoranijwe muri iyi serivisi kugirango birinde kwangirika kw’imiterere.
Muri rusange, ibyuma bya austenitike bitagira umuyonga biterwa na chloride ihangayikishije ruswa muri serivisi ya halide.Nubwo 317L irwanya bimwe bimwe kwihanganira kwangirika kwangirika kurenza 304 / 304L ibyuma bitagira umwanda, kubera molybdenum nyinshi, biracyashoboka.
Chromium yo hejuru, 317 / 317L ibyuma bitarimo ibyuma bya molybdenum hamwe na azote ya 317L byongera ubushobozi bwayo bwo kurwanya imyobo no kwangirika kwa chloride hamwe na halide.Piting Resistance ihwanye harimo numero ya azote (PREN) ni igipimo ugereranije cyo guhangana.Imbonerahamwe ikurikira itanga igereranya Alloy 317L hamwe nibindi byuma bya austenitis.
