Intangiriro

Icyiciro cya 316 nicyiciro gisanzwe cyitwa molybdenum, icyiciro cya kabiri kuri 304 hagati yicyuma cya austenitis.Molybdenum itanga 316 nziza muri rusange irwanya ruswa kurusha icyiciro cya 304, cyane cyane irwanya imyanda no kwangirika kwangirika mubidukikije bya chloride.

Icyiciro cya 316L, verisiyo ya karubone nkeya ya 316 kandi ikingiwe gukangurira (imvura igwa karbide yimvura).Niyo mpamvu ikoreshwa cyane mubice biremereye byo gusudira (hejuru ya 6mm).Muri rusange nta tandukanyirizo ryibiciro rishimishije hagati ya 316 na 316L ibyuma bitagira umwanda.

Imiterere ya austenitis nayo itanga aya manota ubukana buhebuje, ndetse no munsi yubushyuhe bwa cryogenic.

Ugereranije na chromium-nikel austenitis ibyuma bitagira umuyonga, 316L ibyuma bitagira umuyonga bitanga umuvuduko mwinshi, guhangayikishwa no guturika n'imbaraga zikaze ku bushyuhe bwo hejuru.

Ibyingenzi

Iyi mitungo isobanurwa kubicuruzwa bizunguruka (isahani, urupapuro na coil) muri ASTM A240 / A240M.Ibintu bisa ariko ntabwo byanze bikunze bisa nkibindi bicuruzwa nka pipe na bar muburyo bwihariye.

Ibigize

Imbonerahamwe 1. Ibigize bigizwe na 316L ibyuma bitagira umwanda.

Ibikoresho bya mashini

Imbonerahamwe 2. Imiterere ya mashini ya 316L ibyuma bitagira umwanda.

Ibintu bifatika

Imbonerahamwe 3.Imiterere yumubiri isanzwe ya 316 yo mucyuma.

Kugereranya Impamyabumenyi

Imbonerahamwe 4.Itondekanya amanota ya 316L ibyuma bitagira umwanda.

Icyitonderwa: Uku kugereranya kugereranijwe gusa.Urutonde rugenewe nkugereranya ibikoresho bisa nkibikorwa ntabwo aringengabihe ihwanye n'amasezerano.Niba ibisa neza bikenewe ibisobanuro byumwimerere bigomba kubazwa.

Ibishoboka Ibindi Byiciro

Imbonerahamwe 5. Ibishoboka birashoboka amanota 316 ibyuma bitagira umwanda.

Imbonerahamwe 5.Ibishoboka ubundi amanota kugeza 316 ibyuma bidafite ingese.

Icyiciro

Kuki ishobora guhitamo aho kuba 316?

317L

Kurwanya cyane chloride kurenza 316L, ariko hamwe no kurwanya ihungabana ryangirika.

Kurwanya ruswa

Nibyiza cyane mubidukikije byikirere hamwe nibitangazamakuru byinshi byangirika - mubisanzwe birwanya 304. Bitewe no gutobora no kwangirika kwangirika ahantu hashyushye ya chloride, no guhangayikishwa no kwangirika hejuru ya 60°C. Ufatwa nk'urwanya amazi meza hamwe na chloride igera kuri 1000mg / L ku bushyuhe bw’ibidukikije, bikagabanuka kugera kuri 500mg / L kuri 60°C.

316 mubisanzwe bifatwa nkibisanzwe“icyiciro cya marine kitagira ibyuma”, ariko ntabwo irwanya amazi ashyushye yo mu nyanja.Mubidukikije byinshi byo mu nyanja 316 yerekana kwangirika hejuru, mubisanzwe bigaragara nkibara ryijimye.Ibi bifitanye isano cyane na crevices hamwe nubuso butarangiye.

Kurwanya Ubushyuhe

Kurwanya okiside nziza muri serivisi zigihe gito kugeza 870°C no muri serivisi zihoraho kugeza 925°C. Gukomeza gukoresha 316 muri 425-860°C urwego ntirusabwa niba nyuma yo kurwanya amazi yangirika ari ngombwa.Icyiciro cya 316L kirwanya cyane imvura ya karbide kandi irashobora gukoreshwa murwego rwo hejuru rwubushyuhe.Icyiciro cya 316H gifite imbaraga nyinshi mubushyuhe bwo hejuru kandi rimwe na rimwe bikoreshwa muburyo bwimiterere nigitutu kirimo ubushyuhe buri hejuru ya 500°C.

Kuvura Ubushuhe

Umuti wo gukemura (Annealing) - Shyushya 1010-1120°C hanyuma ukonje vuba.Aya manota ntashobora gukomera no kuvura ubushyuhe.

Gusudira

Ubudodo buhebuje nuburyo busanzwe bwo guhuza hamwe nuburyo bwo guhangana, haba hamwe kandi nta byuma byuzuza.Ibice byo gusudira cyane mu cyiciro cya 316 bisaba ko nyuma yo gusudira nyuma yo kurwanya ruswa.Ibi ntibisabwa kuri 316L.

316L ibyuma bidafite ingese ntibishobora gusudwa hakoreshejwe uburyo bwo gusudira oxyacetylene.

Imashini

316L ibyuma bidafite ingese bikunda gukora cyane iyo bikozwe vuba.Kubera iyo mpamvu umuvuduko muke hamwe nigipimo cyibiryo bihoraho birasabwa.

316L ibyuma bidafite ingese nabyo byoroshye kumashini ugereranije nicyuma 316 kitagira umuyonga kubera karuboni nkeya.

Gukora Ubushyuhe n'ubukonje

316L ibyuma bidafite ingese birashobora gushyuha ukoresheje tekinoroji isanzwe ikora.Ubushyuhe bwiza bwo gukora bukwiye kuba buri hagati ya 1150-1260°C, kandi rwose ntigomba kuba munsi ya 930°C. Amaposita yakazi agomba gukorwa kugirango arwanye ruswa.

Ibikorwa byinshi bikonje bikora nko gukata, gushushanya no gushiraho kashe birashobora gukorwa kuri 316L ibyuma bitagira umwanda.Post post annealing igomba gukorwa kugirango ikureho imihangayiko y'imbere.

Gukomera no Gukomera

316L ibyuma bidafite ingese ntibikomera mugusubiza imiti.Irashobora gukomera nakazi gakonje, bishobora no kuvamo imbaraga.

Porogaramu

Porogaramu zisanzwe zirimo:

•Ibikoresho byo gutegura ibiryo cyane cyane mubidukikije bya chloride.

•Imiti

•Porogaramu zo mu nyanja

•Porogaramu yububiko

•Gutera imiti, harimo pin, screw hamwe na orthopedic yatewe nko gusimbuza ikibuno n'amavi

•Kwizirika
