15CrMoG high matsa lamba karfe bututu ingancin tabbaci
15CrMoG karfe bututu ne mai irin sumul karfe bututu, kuma aikinsa ya fi na talakawa sumul karfe bututu. Domin irin wannan nau'in bututun ƙarfe ya ƙunshi ƙarin Cr, ƙarfin zafinsa, ƙarancin zafin jiki da juriya na lalata ba za a iya kwatanta shi da sauran bututun ƙarfe maras sumul ba, don haka ana amfani da bututun gami da yawa a cikin masana'antar mai, masana'antar sinadarai, wutar lantarki, tukunyar jirgi da sauran masana'antu. .
Ka'idar tsarkakewar hydrogen ta bututun karfe na 15CrMoG ita ce lokacin da hydrogen da za a tsarkake aka shigar da shi a gefe guda na bututun karfe na 15CrMoG a 300-500 ℃, ana tallata hydrogen akan bangon bututun karfe 15CrMoG. Saboda rashin electrons guda biyu a cikin 4D electron Layer na palladium, zai iya haifar da haɗin gwiwar sinadarai maras kyau tare da hydrogen (haɗin tsakanin palladium da hydrogen yana canzawa). A karkashin aikin palladium, hydrogen yana ionized zuwa protons tare da radius na 1.5 × 1015m, yayin da kullun palladium shine 3.88 × 10-10m (a 20 ℃), yana iya wucewa ta cikin bututun ƙarfe na 15CrMoG. Karkashin aikin palladium, protons suna haɗuwa da electrons kuma suna sake samar da kwayoyin hydrogen, waɗanda ke tserewa daga ɗayan ɓangaren bututun ƙarfe na 15CrMoG. A saman 15CrMoG gami da bututun ƙarfe, iskar da ba a haɗa ta ba ba za ta iya wucewa ba, don haka ana iya amfani da bututun ƙarfe na 15CrMoG don samun hydrogen mai tsafta.
Ko da yake palladium yana da keɓantacce na musamman ga hydrogen, tsarkakakken palladium yana da ƙayyadaddun ƙayyadaddun kayan aikin injiniya, sauƙin iskar shaka a babban zafin jiki da ƙarancin recrystallization, wanda ke da sauƙin nakasa da ƙwanƙwasa bututun ƙarfe na 15CrMoG. Sabili da haka, ba za a iya amfani da palladium mai tsabta a matsayin membrane mai lalacewa ba. Ƙara adadin abubuwan da suka dace na IB da VIII zuwa palladium don yin alluran palladium na iya haɓaka kayan aikin injiniya na palladium. 11. Sumul karfe bututu for mota rabin axle hannun riga (gb3088-82) ne a high quality-carbon tsarin karfe da gami tsarin karfe zafi-birgima sumul karfe bututu ga Manufacturing mota rabin axle hannun riga da kuma fitar da axle gidaje. A cikin palladium alloy, azurfa yana da kusan 20-30%, kuma abubuwan da ke cikin sauran abubuwan (kamar zinari, da sauransu) bai wuce 5% ba.
① Lambobi biyu a farkon matakin karfe suna wakiltar abun cikin carbon na karfe, wanda aka bayyana a matsayin 'yan dubbai na matsakaicin abun ciki na carbon, kamar 40Cr.
②Babban abubuwan haɗakarwa a cikin ƙarfe, ban da daidaikun abubuwan microalloyed, gabaɗaya ana bayyana su cikin ƴan kashi. Lokacin da matsakaita abun ciki na gami bai wuce 1.5% ba, gabaɗaya alamar kashi kawai ake yiwa alama a cikin ma'aunin ƙarfe, amma abun cikin ba a yiwa alama alama ba. Duk da haka, idan yana da sauƙi a ruɗe a ƙarƙashin yanayi na musamman, lambar "1" kuma ana iya yin alama bayan alamar kashi, kamar ma'aunin ƙarfe "12CrMoV" da "12Cr1MoV". Abubuwan da ke cikin chromium na tsohon shine 0.4-0.6%, kuma na ƙarshen shine 0.9-1.2%, sauran abubuwan da aka haɗa duka iri ɗaya ne. Lokacin da matsakaicin abun ciki na abubuwan gami ya kasance ≥ 1.5%, ≥ 2.5%, ≥ 3.5% ... Za a nuna abun ciki bayan alamar kashi, wanda za'a iya bayyana shi azaman 2, 3, 4 ... da sauransu. Misali, 18Cr2Ni4WA.
③Vanadium V, titanium Ti, aluminum Al, boron B, rare earth RE da sauran abubuwan gami a cikin ƙarfe suna cikin abubuwan microalloyed. Ko da yake abun ciki yana da ƙasa sosai, ya kamata a yi musu alama a cikin ƙimar ƙarfe. Misali, a cikin karfe 20mnvb. 0.07-0.12% na vanadium da 0.001-0.005% na boron.
④ Ƙarfe mai inganci za a yi masa alama da "a" a ƙarshen ƙimar ƙarfe don bambanta shi da babban ingancin ƙarfe na gaba ɗaya.
⑤Don ƙaƙƙarfan tsarin ƙarfe don manufa ta musamman, ƙimar ƙarfe tana gaba da (ko kari) don wakiltar alamar manufar ƙarfen. Misali, karfe 30CrMnSi don dunƙule riveting ana wakilta shi azaman ml30crmnsi.
Alloy bututu da bututu maras kyau suna da alaƙa da bambance-bambance, kuma ba za a iya rikicewa ba. Alloy bututu wani nau'i ne na bututu maras sumul. Kodayake ba za a iya haɗa shi ba, bututu maras nauyi ya haɗa da bututun gami.
Alloy bututu an bayyana shi azaman bututun ƙarfe bisa ga kayan samarwa (watau abu). Kamar yadda sunan ya nuna, bututu ne da aka yi da gami; An bayyana bututu maras kyau bisa ga tsarin samar da bututun ƙarfe (seamless seam). Abin da ya bambanta da bututu maras sumul shine bututu maras kyau, gami da madaidaiciyar bututun welded da bututu mai karkace.
