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.
Ka oati ta maatau umanga ki nga kaihoko katoa mai i nga otinga akomanga tuatahi me te kamupene whai muri i te hokonga tino pai.Ka tino mihi matou ki o taatau kiritaki hou, hou hoki ki te whakauru mai ki a matou mo te Hot / Cold Rolled ASTM 42CrMo Q355b SAE1020 1045 1035 1052 Seamless Steel Pipe mo te Tika / Porohita / Hollow / Galvanized / Black / Carbon Tube / Alloy Steel Pipe, Kua koa matou kei te piki haere tonu matou ma te whakamahi i te awhina kaha me te wa roa a o maatau kaihoko pai!
Ka oati ta maatau umanga ki nga kaihoko katoa mai i nga otinga akomanga tuatahi me te kamupene whai muri i te hokonga tino pai.Ka tino mihi matou ki o taatau kiritaki hou me nga kaihoko hou kia uru mai ki a maatauHaina Paipa maitai me te ngongo, Kei te tumanako matou ki te whakatu i tetahi hononga whai hua ki a koe i runga i o maatau taonga kounga teitei, utu whaitake me te ratonga pai.Ko te tumanako ka kawea mai e a maatau hua he wheako pai ki a koe me te kawe i te ahua o te ataahua.
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.
