Nō nā tata nei, i tukuna te paerewa ā-motu GB/T20878-2024 "Ngā Tohu Rino Kowiri tira me ngā Hanganga Matū", i whakatikahia e te Metallurgical Industry Information Standards Research Institute me te whai wāhi atu a Fujian Qingtuo Special Steel Technology Research Co., Ltd. me ētahi atu waeine, ā, ka whakatinanahia i te 1 o Pēpuere, 2025. I muri i te tata ki te ono tau o ngā mahi uaua, i whakawhanake motuhake a Qingtuo Group i te raupapa QN maitai kore waikura austenitic tino kaha kei roto te hauota, tae atu ki te S35250 (QN1701), S25230 (QN1801), S35657 (QN1803), S35656 (QN1804), S35388 (Kua whakaurua ngā hua me ngā taumata ātete waikura rerekē pērā i te QF1804), S35706 (QN2008), S35886 (QN1906) me te S35887 (QN2109) ki tēnei paerewa, e whakarei ake ana i te hanganga momo maitai kore waikura me te whakarato i te kaha teitei, te mama, me te ātete waikura teitei mō te mara o ngā hanganga pikau kawenga. Ko te mahere whakatinanatanga o ngā momo maitai kore waikura me te haumaru teitei me te whai hua utu.
Ko te S35656 (QN1804) e whakawhirinaki ana ki tōna ātete pai ki te waikura, ki te kaha ki te whakarewa me ngā āhuatanga miihini pāmahana iti kia whakaurua ki roto i te GB/T150.2-2024 "Ngā Ipu Pēhanga Wāhanga 2: Ngā Rauemi" me te GB/T713.7-2023 "Pereti Rino me te Rino mō ngā Taputapu Pēhanga" Me te Wāhanga 7: Rino Kowiri tira me te Rino Ātete-Wera" me ētahi atu paerewa ā-motu e rua e pā ana ki ngā ipu pēhanga. I ngā tau kua pahure ake nei, kua hangaia e te rino kowiri tira raupapa QN he mekameka ahumahi pumau, ā, kua whakamahia i roto i ngā puranga i roto i ngā mara mākete hanganga kawenga maha pērā i te hangarau kauhanga tereina tereina tereina, ngā whare kua oti te hanga, te hangarau raro whenua, te pūngao, te hangarau moana me ngā ipu pēhanga.
Te whakakanapa hikoHe tukanga whakaoti hikohiko e tango ana i tētahi paparanga angiangi o te rauemi mai i tētahi wāhanga whakarewa, ko te nuinga he kowiri tira, he koranu rite rānei. Ka waiho e te tukanga he mata kanapa, he maeneene, he tino ma.
E mōhiotia ana hoki kote whakakanapa hikohiko, te whakakanapa anodicrāneite whakakanapa hikohiko, he tino whai hua te whakakanapa hiko mō te whakakanapa me te tango i ngā pakarukaru o ngā wāhanga pakarukaru, ngā āhua uaua rānei. Ka whakapai ake te whakakanapa hiko i te whakaotinga o te mata mā te whakaiti i te taratara o te mata tae atu ki te 50%.
Ka taea te whakaaro ki te whakakoi hiko heite whakakikoruatanga hiko whakamuriEngari ko te whakakoi hiko, ka whakamahia e ia te iahiko hei whakarewa i tētahi paparanga angiangi o ngā katote konganuku kua utua pai ki roto i tētahi otinga irahiko.
Ko te whakakanapa hiko o te rino kore waikura te whakamahinga tino noa o te whakakanapa hiko. He maeneene, he kanapa, he tino ma te āhua o te rino kore waikura e ātete ana ki te waikura. Ahakoa e pai ana te nuinga o ngā konganuku, ko ngā konganuku e whakakanapahia ana ko te rino kore waikura raupapa 300- me te 400-raupapa.
He rerekē ngā paerewa o te whakaotinga o te whakakikorua hiko mō ngā mahi rerekē. Me whakamahi ēnei mahi i te whānuitanga whakaotinga waenga. Ko te whakakanapa hiko he tukanga e whakaiti ana i te taratara o te paipa maitai kore-whakakanapa hiko. Mā tēnei ka tika ake ngā rahi o ngā paipa, ā, ka taea te tāuta i te paipa EP me te tika i roto i ngā pūnaha tairongo pērā i tengā tono ahumahi rongoā.
Kei a mātou ā mātou ake taputapu whakakanapa, ā, e whakaputa ana i ngā ngongo whakakanapa hiko e tutuki ai ngā whakaritenga o ngā momo mara i raro i te arataki a te tīma hangarau o Korea.
Ko tā mātou Ngongo EP i roto i ngā āhuatanga rūma ma ISO14644-1 Akomanga 5, ka horoia ia ngongo kitino parakore (UHP)hauota, kātahi ka taupokina, ka tāpirihia ki roto i ngā putea takirua. Ka whakaratohia he tiwhikete e whakamana ana i ngā paerewa whakaputa o te ngongo, te hanganga matū, te whai i ngā rauemi, me te taratara o te mata mōrahi mō ngā rauemi katoa.
