Whakaahuatanga Poto:
42CrMo koranu putorino tuitui ko te ultra-tiketike rawa maitai ki te kaha teitei me te uaua, pai hardenability, kahore he brittleness tempering kitea, me te deformation iti i te tineia.I muri i te tinei me te whakamahana, 42CrMo koranu putorino tuitui he tepe rohirohi nui me te maha o nga paanga o te atete, he pai te kaha o te paanga ki te iti o te pāmahana, me te kaha o te ngokingoki me te kaha mau tonu i te pāmahana teitei.Ko te tiini o te mata i muri i te tiini me te whakamahana ka whakamahia hei kaupapa maimoatanga wera mo te 42CrMo koranu paipa kore.
I whakatapua ki te tino whakahaere kounga me te ratonga kiritaki whai whakaaro, kei te waatea tonu o maatau kaimahi mohio ki te matapaki i o whakaritenga me te whakarite kia tino makona nga kaihoko mo te wheketere mo te Kaihanga Kaihoko Tika 42CrMo Alloy Seamless Steel Pipe Nui-Diameter Matotoru Wall iti Alloy Pipe Boilers Steel Pipe, In Mena kei a koe etahi arotake e pa ana ki ta maatau whakahaere, taonga ranei, kia mohio koe ki te whai waahi ki te korero ki a maatau, ka tino mihihia to mēra e haere mai ana.
I whakatapua ki te tino whakahaere kounga me te ratonga kaihoko whakaaro nui, kei te waatea tonu a maatau kaimahi mohio ki te korero mo o hiahia me te whakarite kia pai nga kaihoko moNga Paipa Tira Kore o Haina me te Tuepu maitai a tawhio noa, Ko te ratonga whai muri tonu me te tohungatanga i tukuna mai e to maatau roopu kaitohutohu he harikoa o taatau kaihoko.Ko nga korero hohonu me nga tawhā mai i nga taonga hokohoko ka tukuna atu maau mo te mohiotanga matawhānui.Ka tukuna pea he tauira kore utu ka tirohia e te kamupene ki ta maatau kaporeihana.n Morocco mo te whiriwhiringa he powhiri tonu.Ko te tumanako ka patai atu koe ki a koe me te hanga i tetahi hononga mahi tahi mo te wa roa.
Karekau he ahua ngoikore o te riri, he iti te whakarereketanga i te wa e tineia ana, te rohe rohirohi nui me te maha o nga awangawanga i muri i te tiini me te whakamaarama.42CrMo koranu putorino tui he pai te awe o te uaua i te iti o te pāmahana me te kaha o te ngokingoki me te kaha mau tonu i te pāmahana teitei.Ko te tiini o te mata i muri i te tiini me te whakamahana ka whakamahia hei kaupapa maimoatanga wera mo te 42CrMo koranu paipa kore.
Te maitai motuhake: 41Cr4,25CrMo4,30CrMo4,34CrMo4,42CrMo4
OD: 20-660mm WT: 2.3-100mm L: 5.8M, 6M, 11.8M, 12M ranei tetahi atu roa kua tohua.
Taupānga: Hangaia, Hangarau Whānui, ringa warou, Ngaherehere, He rereke nga Porotakaro, Nga Roera Kaikawe, Nga Waahi Hollow, Nga Waahi Hollow me nga waahanga, Nati, Mowhiti, aha atu
Te whakamahi i te putorino tuitui 42CrMo: ko te maitai motuhake e whakamahia ana mo nga piriti ko "42CrMo", ko te maitai motuhake mo nga whitiki motuka ko "42CrMo", me te maitai motuhake mo nga oko pehanga ko "42CrMo".Ko tenei momo rino ka whakapai ake i nga ahuatanga miihini o te maitai ma te whakatikatika i te waro (c) ihirangi.Na reira, kia rite ki te ihirangi waro, ka taea te wehea tenei momo maitai ki: iti waro maitai - te ihirangi waro ko te tikanga iti iho i te 0.25%, pērā i te 10 me te 20 maitai;Wao waro waro - te tikanga kei waenganui i te 0.25 me te 0.60% te ihirangi waro, penei i te 35 me te 45 te maitai;Te waro maitai teitei — te nuinga o te waro he nui ake i te 0.60%.Ko tenei momo maitai kaore i te whakamahia hei hanga paipa maitai.
Taupānga Angamaheni
He pai mo te hanga i nga miihini kirihou nui me te reo-rahi e hiahia ana kia kaha me te uaua.
