Umuyoboro w'icyuma udafite icyerekezo (GB / T8162-2008) ikoreshwa muburyo rusange nuburyo bwubukanishi bwicyuma kitagira icyuma.

Ikoreshwa mugukora ibyuma bidafite icyuma kubikoresho, imiyoboro, ibikoresho, ibikoresho hamwe nubukanishi

Ubwubatsi: imiterere ya salle, trestle yinyanja, imiterere yikibuga cyindege, dock, urugi rwumutekano, urugi rwa garage, inzugi zometseho ibyuma hamwe na Windows, urukuta rwigice cyimbere mu nzu, imiterere yikiraro cya kabili hamwe nabashinzwe umutekano wumuhanda, gariyamoshi, imitako, gutura, imiyoboro ishushanya.

Ibice by'imodoka: gukora imodoka na bisi, ibikoresho byo gutwara

Ubuhinzi: Ibikoresho byubuhinzi

Inganda: Imashini, Inkunga izuba, umurima wa peteroli yo hanze, ibikoresho byubucukuzi, ibikoresho bya mashini n amashanyarazi, Ubwubatsi, ubucukuzi, uburemere nubutunzi, gutunganya Ubwubatsi, gutunganya ibikoresho, ibice byubukanishi

Ubwikorezi: gariyamoshi y'abanyamaguru, izamu, inyubako ya kare, ibyapa, ibikoresho byo mumuhanda, uruzitiro

Kubika ibikoresho: ububiko bwa supermarket, ibikoresho, ibikoresho byishuri

Urwego nyamukuru rwicyuma

Q345, 15CrMo, 12Cr1MoV, A53A, A53B, SA53A, SA53B

Ingano yicyuma idafite ubunini kandi iremewe gutandukana

Umuyoboro wa karubone (GB / 8162-2008)

Ubu bwoko bwicyuma cyubatswe muburyo busanzwe bushongeshwa nu guhinduranya cyangwa gucana, ibikoresho byingenzi byingenzi ni icyuma gishongeshejwe nicyuma gisakara, ibirimo sulfure na fosifore mubyuma biruta iby'icyuma cyiza cya karubone cyiza cyane, muri rusange sulfure ≤0.050 %, fosifore ≤0.045%.Ibiri mubindi bintu bivangavanze, nka chromium, nikel n'umuringa, byazanywe mu byuma n'ibikoresho fatizo muri rusange ntabwo birenga 0,30%.Ukurikije ibihimbano n'ibisabwa, icyiciro cyubwoko bwicyuma cyubatswe cyerekanwa nicyiciro cya Q195, Q215A, B, Q235A, B, C, D, Q255A, B, Q275 nibindi.

Icyitonderwa: "Q" ni inyuguti ya fonetike yubushinwa yumusaruro "qu", ikurikirwa nigiciro gito cyumusaruro (σ S) agaciro kamanota, ugakurikirwa nikimenyetso ukurikije ibintu byanduye (sulfure, fosifore) biva hejuru kugeza hasi hamwe nimpinduka mubintu bya karubone na manganese, byashyizwe mubyiciro bine A, B, C, D.

Ubu bwoko bwibyuma byubatswe nibisohoka nini, ikoreshwa ni ryagutse cyane, iringaniye cyane mu isahani, umwirondoro (uruziga, kare, igorofa, akazi, groove, Inguni, nibindi) hamwe nu mwirondoro no gukora imiyoboro yo gusudira.Ahanini ikoreshwa mumahugurwa, ikiraro, ubwato nizindi nyubako zubaka hamwe nu miyoboro rusange yo gutwara amazi.Ubu bwoko bwibyuma bikoreshwa muburyo butaziguye bwo kuvura ubushyuhe.

Umuyoboro muke ufite imbaraga zo kubaka ibyuma (GB / T8162-2008)

Usibye umubare munini wa silikoni cyangwa manganese, imiyoboro y'ibyuma irimo ibindi bintu bikwiranye n'umutungo w'Ubushinwa.Nka vanadium (V), niobium (Nb), titanium (Ti), aluminium (Al), molybdenum (Mo), azote (N), hamwe nubutaka budasanzwe (RE).Ukurikije imiterere yimiti nibisabwa, urwego rwayo rugereranwa na Q295A, B, Q345A, B, C, D, E, Q390A, B, C, D, E, Q420A, B, C, D, E, Q460C, D , E nibindi byiciro byibyuma, kandi ibisobanuro byayo ni kimwe na karubone yubatswe ibyuma.

Usibye icyiciro cya A na B ibyuma, icyiciro C, GRADE D nicyiciro cya E bigomba kuba byibuze kimwe mubintu bitunganijwe neza nka V, Nb, Ti na Al.Kugirango tunoze imikorere yicyuma, A, B urwego rwicyuma narwo rushobora kongerwaho imwe murimwe.Mubyongeyeho, ibintu bisigaye bigize Cr, Ni na Cu biri munsi ya 0,30%.Q345A, B, C, D, E ni amanota ahagarariye ubwoko bwibyuma, muribo ibyuma byo mu rwego rwa A, B bikunze kwitwa 16Mn;Ibintu birenga kimwe bigomba kwongerwaho kurwego C no hejuru yicyuma, kandi imitungo imwe yubushyuhe bwo hasi igomba kongerwaho mumikorere yubukanishi.

Ikigereranyo cyubu bwoko bwicyuma cyubatswe nicyuma cyubaka ibyuma.Ifite ibyiza byimbaraga nyinshi, imikorere myiza yuzuye, ubuzima bwa serivisi ndende, uburyo bwagutse bwo gukoresha hamwe nubukungu bugereranya.Ikoreshwa cyane muri Bridges, amato, amashyiga, ibinyabiziga ninyubako zingenzi zubaka.
