Te Whakauru i te Mekameka Hiki SCIC Grade 80 (G80): Te Hurihanga i te Ahumahi Hanga Mekameka
I roto i te ao tere o te hiki me te here ahumahi, he mea nui te mahi a ngā mekameka hei whakarite i te haumaru me te whai huatanga. Mō ngā tau, kua herea te umanga mekameka ki ngā kōwhiringa iti iho te kounga, nā te koretake o ngā mira Haina ki te whakawhanake i ngā maitai koranu kaha-teitei. Heoi, i te whakaurunga mai o te mekameka Grade 80 (G80) a SCIC, kua ngaro tēnei herenga ināianei.
Kua hangaia ngā mekameka hiki SCIC Grade 80 (G80) kia tutuki ai ngā paerewa ahumahi teitei rawa atu. I hangaia kia rite ki te EN 818-2, he mea hanga ēnei mekameka ki te maitai koranu nickel-chromium-molybdenum-manganese, ā, e whai ana i te paerewa DIN 17115 tino pakari. Ko te hua he mekameka e whakakotahi ana i te kaha tino pai me te manawanui tino pai.
Ko tētahi o ngā āhuatanga matua o te mekameka SCIC Grade 80 (G80) ko tōna tukanga whakarewa me te whakamahana i hangaia me te āta tirotirohia. Mā ēnei tukanga ka tino pai ngā āhuatanga miihini o te mekameka, tae atu ki te ātete pai ki te kakahu me te ngenge. Mā ēnei tukanga pakari ka tino pai te kaha whakamātautau, te kaha whati, te roa me te pakeke o te mekameka.
Kāwai
He maha ngā whakamahinga o tēnei hua hou i roto i ngā umanga hiki me te here. Ahakoa e whakamahia ana i roto i ngā taura mekameka, i roto rānei i te mekameka taura, ka tukuna e te mekameka SCIC Grade 80 (G80) te kaha me te pono kāore e taea te whakataurite. Ko tōna hoahoa hononga poto me te porowhita ka whakarei ake i tōna ngāwari me te hototahi ki ngā taputapu hiki rerekē.
Hei tāpiritanga, he mea hanga motuhake ngā mekameka SCIC Grade 80 (G80) mō ngā taura mekameka, ā, e tutuki ana i te DIN 818-2 Mekameka Manawanui Waenga e ai ki te whakaritenga Akomanga 8 mō ngā taura mekameka. Mā tēnei ka taea e te mekameka te tu atu ki ngā kawenga taumaha me te kore e whakararu i te haumaru, i te mahi rānei.
Kei te huri haere te umanga hanga mekameka me te whakaurunga mai o ngā mekameka hiki SCIC Grade 80 (G80). Kāore e herea ki ngā kōwhiringa kounga iti iho, ka taea e ngā kamupene te whakawhirinaki ki te kaha me te pakari o ēnei mekameka maitai koranu mō ā rātou hiahia hiki me te here. Ko te kounga teitei o ngā mekameka SCIC Grade 80 (G80) e oati ana i te haumaru nui ake, te hua teitei ake me te pai ake o te mahi.
Hei whakarāpopototanga, kua kawea mai e ngā mekameka SCIC Grade 80 (G80) he whanaketanga nui ki te umanga hanga mekameka. Nā ōna āhuatanga miihini pai rawa atu, te tutuki i ngā paerewa ahumahi me te whakamahinga maha, he mea tino pai mō te hiki me te here. Awhitia te heke mai o te hangarau mekameka me te mekameka SCIC Grade 80 (G80) ka wheako i te rerekētanga o te mahi me te pono.
