He aha te Whakapakari Ua o te Kowiri tira?
Ko te maitai kore waikura whakapakeke ua, e kiia ana ko te "PH stainless steel," he momo maitai kore waikura e pāngia ana e te tukanga e kiia nei ko te whakapakeketanga ua, te whakapakeketanga tawhito rānei. Ka whakarei ake tēnei tukanga i ngā āhuatanga hangarau o te rauemi, inā koa tōna kaha me tōna pakeke. Ko te maitai kore waikura whakapakeketanga ua tino noa ko17-4 PH(ASTM A705 Kaute 630), engari ko ētahi atu kare ā-roto, pērā i te 15-5 PH me te 13-8 PH, ka taka hoki ki tēnei kāwai. Ko ngā maitai kore waikura whakapakeke ua ka whakakoihia ki ngā huānga pērā i te chromium, te nickel, te parahi, me te konumohe i ētahi wā. Mā te tāpiri i ēnei huānga whakakoi ka whakatairanga i te hanganga o ngā matū i te wā o te tukanga maimoatanga wera.
Me pēhea te whakapakeketanga o te rino kore waikura?
E toru ngā taahiraa o te whakapakeketanga o te maitai kore waikura. I te tīmatanga, ka tukuna te rauemi ki te maimoatanga otinga pāmahana teitei, ka rewa ngā ngota matū, ka hanga he otinga kotahi-wāhanga. Ka hua ake tēnei i te hanganga o ngā karihi moroiti maha, ngā "rohe" rānei i runga i te konganuku. Muri iho, ka tere te whakamatao i tua atu i te rohe wairewa, ka hangaia he otinga totoka tino mātotoru i roto i te āhua pumau. I te taahiraa whakamutunga, ka whakamahanahia te otinga tino mātotoru ki te pāmahana waenga, ka puta te ua. Kātahi ka puritia te rauemi ki tēnei āhua tae noa ki te whakapakeketanga. Ko te whakapakeketanga angitu me noho te hanganga koranu i roto i te rohe wairewa, kia pai ai te whai huatanga o te tukanga.
He aha ngā momo maitai whakapakeke kua whakapakeketia?
He maha ngā momo maitai whakapakeke-ua, ia momo e hāngai ana ki ngā whakaritenga mahi me te tono. Ko ngā momo noa ko te 17-4 PH, 15-5 PH, 13-8 PH, 17-7 PH, A-286, Ritenga 450, Ritenga 630 (17-4 PHMod), me Carpenter Custom 455. He huinga o te kaha teitei, te ātete ki te waikura, me te pakeke o ēnei maitai, e pai ai mō ngā ahumahi kanorau pēnei i te rererangi, te motuka, te hauora, me te tukatuka matū. Ko te whiriwhiri i te maitai whakapakeke-wai e whakawhirinaki ana ki ngā āhuatanga pēnei i te taiao tono, te mahi rauemi, me ngā whakaritenga hanga.
Te tākai:
1. He mea nui te tākai, inā koa mō ngā tukunga o tāwāhi e haere ana ngā uta mā roto i ngā huarahi rerekē kia tae atu ki te ūnga whakamutunga, nō reira ka tino aro nui mātou ki te tākai.
2. He maha ngā huarahi e tākai ai a Saky Steel i ā mātou taonga, e ai ki ngā hua. He maha ngā huarahi e tākai ai mātou i ā mātou hua, pērā i,
