Ngā pātai e pātaihia pinepinetia ana mō te maitai

He aha te maitai, ā, me pēhea te hanga?
Ina whakaranua te rino ki te waro me ētahi atu huānga, ka kiia he maitai. Ko te maitai ka puta mai he whakamahinga matua mō ngā whare, ngā hanganga, ngā taputapu, ngā kaipuke, ngā motuka, ngā mīhini, ngā momo taputapu me ngā patu. He maha ngā whakamahinga nā te kaha o te kume o ngā maitai, ā, he iti hoki te utu.

Nā wai i kite?
Kua kitea ngā tauira tuatahi o te maitai i Turkey, ā, i ahu mai i te tau 1800 BC. Ko te hanga maitai o ēnei rā i ahu mai i a Tā Henry Bessemer o Ingarangi, nāna i kitea he tikanga hanga nui, he iti hoki te utu.

Ko Jindalai Steel Group tētahi o ngā kaihanga me ngā kaihokohoko matua o te koiri/pepa/pereti/rīpene/paipa maitai kore waikura.

He aha te rerekētanga i waenga i te Rino me te Maitai?
He huānga tūturu te rino e kitea ana i roto i te taiao i roto i te Kore Rino. Ko te rino te wāhanga matua o te maitai, he koranu rino me te tāpiritanga matua o te maitai. He kaha ake te maitai i te rino, he pai ake ōna āhuatanga kume me te pēhi.

He aha ngā āhuatanga o te maitai?
● He kaha te kume o te maitai
● He ngāwari te whakapiko – e āhei ai te hanga ngāwari
● Te pakari – e āhei ai te maitai ki te tu atu i ngā kaha o waho.
● Te kawe hiko – he pai ki te kawe i te wera me te hiko, he mea whai hua mō ngā taputapu tunu kai me ngā waea.
● Kanapa – he ātaahua te āhua o te maitai, he hiriwa.
● Ātete Waikura – mā te tāpiri i ngā momo huānga rerekē i roto i ngā ōrau rerekē ka taea te hoatu he ātete waikura teitei ki te maitai i roto i te ahua o te maitai kore waikura.

Ko tēhea te mea kaha ake, te maitai, te titanium rānei?
Ina honoa ki ētahi atu konganuku pēnei i te konumohe, te vanadium rānei, he kaha ake te koranu titanium i te maha o ngā momo maitai. Mō te kaha rawa atu, ka hinga ake ngā koranu titanium pai rawa atu i ngā maitai kore waikura kounga iti ki te waenga. Heoi, he kaha ake te kounga teitei o te maitai kore waikura i ngā koranu titanium.

He aha ngā momo maitai e whā?
(1) Te maitai waro
Kei roto i ngā maitai waro te rino, te waro, me ētahi atu huānga whakarewa pērā i te manganese, te silicon, me te parahi.
(2) Rino Koranu
Kei roto i ngā maitai koranu ngā konganuku koranu noa i ngā ōwehenga rerekē, ā, nā reira e tika ai tēnei momo maitai mō ngā whakamahinga motuhake.
(3) Kowiri tira
Ahakoa he maha ngā koranu whakarewa kei roto i ngā maitai kore waikura, he 10-20 ōrau te chromium kei roto, koia te huānga koranu matua. Ki te whakatauritea ki ētahi atu momo maitai, e 200 ngā wā ka nui ake te ātete o ngā maitai kore waikura ki te waikura, inā koa ko ngā momo kei roto i te 11 ōrau te chromium.
(4) Rino Utauta
Ka whakakoihia tēnei momo maitai ki ngā pāmahana tino teitei, ā, he maha ngā wā kei roto ngā konganuku mārō pērā i te tungsten, te cobalt, te molybdenum, me te vanadium. Nā te mea ehara i te mea he ātete wera anake engari he pakari hoki, ka whakamahia ngā maitai taputapu mō te tapahi me te keri taputapu.

Ko tēhea te māka tino kaha?
Ko te SUS 440 – he maitai kounga teitei ake o te maitai tapahi, he nui ake te ōrau waro, ā, he pai ake te pupuri i ngā taha ina tika te whakamahana. Ka taea te whakapakeke ki te pakeketanga o Rockwell 58, koia tētahi o ngā maitai kore waikura tino mārō.

He aha te take kāore te rino i kiia ai he konganuku?
Ko tētahi o ngā pātai e pātaihia pinepinetia ana mō te maitai, he aha te take kāore te maitai i te whakarōpūtia hei konganuku? Ko te maitai, he koranu, nō reira ehara i te huānga parakore, ehara i te mea he konganuku engari he momo kē atu. He wāhanga o te mea he konganuku, he rino, engari nā te mea he waro kore-konganuku anō hoki kei roto i tōna hanganga matū, ehara i te konganuku parakore.

Ko tēhea te momo e whakamahia nuitia ana?
Ko te maitai kore waikura 304, ko te SUS 304 rānei te momo tino noa; ko te maitai kore waikura 18/8 (18% chromium, 8% nickel) matarohia. I waho o te US, e mōhiotia whānuitia ana ko te "A2 stainless steel", e ai ki te ISO 3506 (kaua e whakapoauau ki te maitai taputapu A2)

He rauemi pumau te maitai?
He rauemi ahurei te rino, ā, he mea pumau tonu, nā te mea i muri i te hanganga, ka taea te whakamahi hei rino mō ake tonu atu. Ka taea te hangarua tonu i te rino, nō reira kāore e moumou te haumitanga ki te hanga rino, ā, ka taea te whakamahi mō ngā whakatipuranga o muri mai.

Ētahi kōrero whakamere mō te maitai
● Ahakoa he rauemi kaha te rino i a ia anō, ka taea e te maitai te 1000 ngā wā kaha ake i te rino.
● Ka pōturi, ka mutu rānei te waikura o te maitai ina rere te iahiko i roto i te maitai. E mōhiotia ana tēnei ko te Tiakitanga Katorika, ā, e whakamahia ana mō ngā paipa, ngā kaipuke, me te maitai i roto i te raima.
● Ko te rino te rauemi hangarua rawa atu i Amerika Te Raki – tata ki te 69% o taua mea ka hangaruahia i ia tau, he nui ake i te kirihou, te pepa, te konumohe, me te karāhe whakakotahi.
● I te tau 1883 i whakamahia tuatahitia ai te rino mō ngā whare teitei.
● E kore e hiahiatia he rakau o ngā rākau e 40 hei hanga i tētahi whare anga rakau – e 8 ngā waka hangarua e whakamahia ana e tētahi whare anga maitai.
● I hangaia te motuka maitai tuatahi i te tau 1918
● E 600 ngā kēne rino, ngā kēne tine rānei ka hangaruatia i ia hēkona.
● E 83,000 tāne o te maitai i whakamahia hei hanga i te Piriti o Golden Gate.
● Kua heke te nui o te pūngao e hiahiatia ana hei hanga i te kotahi tana o te maitai ki te haurua i roto i ngā tau 30 kua pahure ake nei.
● I te tau 2018, ko te tapeke o te hanga maitai mata o te ao i eke ki te 1,808.6 miriona tāne. He rite tēnei ki te taumaha o te 180,249 o ngā Pourewa Eiffel.
● Tērā pea kei te karapotia koe e te rino i tēnei wā. Ko te 65% o ngā taputapu whare he mea hanga mai i ngā hua rino.
● Kei roto hoki i ō hikohiko te rino! O ngā rauemi katoa e hanga ana i tētahi rorohiko noa, tata ki te 25% he rino.
