He aha te rite me te rerekētanga o te maitai me te kowiri tira?

Ko te rino tētahi o ngā rauemi tino nui o te ahumahi hou, koia te poutokomanawa o te hanganga, te kawe waka, te whakangao, me te tini o ngā tono. He rite tonu te hiranga o te rino kore waikura, he wāhanga o te rino, inā koa i ngā taiao e tino hira ana te ātete ki te waikura, te akuaku, me te pakari. Ahakoa he maha ngā āhuatanga ōrite o ngā rauemi e rua, he rerekē anō hoki te hanganga, ngā āhuatanga, me ngā tono.

Ki ngā kaihangarau, ki ngā tohunga hokohoko, me ngā kaihanga, he mea nui te mārama ki te ōritetanga me te rerekētanga o te maitai me te kowiri tira hei whiriwhiri i te rauemi tika mō ia kaupapa.

He aha te maitai?

He koranu te rino, he mea hanga tuatahi ki te rino me te waro. Mā te whakarerekē i te nui o te waro me te tāpiri i ētahi atu huānga, ka taea e ngā kaihanga te hanga i ngā maitai me ngā āhuatanga rerekē pēnei i te pakeke, te kaha, me te ngāwari.

Ngā momo maitai

• maitai waroKei roto te rino me te waro, mai i ngā momo rino waro-iti (te maitai ngawari) ki ngā momo maitai waro-nui.

• Rino KoranuKei roto ko ngā huānga tāpiri pērā i te chromium, te nickel, te molybdenum, te vanadium rānei hei whakapakari i te kaha me te pakari.

• Rino Utauta: I hangaia mō te pakeke me te ātete ki te kakahu, e whakamahia whānuitia ana mō ngā taputapu tapahi me te hanga.

• Rino HangangaWhakamahia ai mō ngā kurupae, ngā pou, me ngā anga.

He aha te Kowiri tira?

He momo maitai motuhake te maitai kore waikura kei roto i te iti rawa10.5% konukōmiumamā te taumaha. Ka tauhohe te chromium ki te hāora i te rangi hei hanga i tētahi paparanga angiangi, kāore e kitea o te chromium oxide i runga i te mata, e mōhiotia ana ko te kiriata kore mahi. Ka tiaki tēnei kiriata i te maitai mai i te waikura me te pirau, ka motuhake ai te maitai kore waikura ki te whakataurite ki ngā maitai waro me te koranu.

Ngā Momo Kowiri tira noa

• Kowiri tira Austenitic (304, 316)He tino ātete ki te waikura, he tino pai mō ngā mahi kai, moana, me ngā mahi matū.

• Kowiri tira Ferritic (430)He iti ake te utu, he ātete pai ki te pakaru waikura.

• Kowiri tira Martensitic (410, 420)He tino kaha, he tino mārō hoki, e whakamahia ana i roto i ngā taputapu kai me ngā taputapu pokanga.

• Kowiri tira takirua (2205, 2507): Ka whakakotahi i te kaha me te ātete pai ki te hauota.

Ngā Rerekētanga i waenga i te Rino me te Rino Kowiri tira

1. Ātete ki te Waikura

• RinoKa ngawari ki te waikura me te waikura, ki te kore he paninga tiaki.

• Kowiri tiraHe ātete ā-taiao ki te waikura nā te mea kei roto i te paparanga waikura chromium.

2. Āhua

• RinoHe āhua pōuri ake, he āhua mōhinuhinu te nuinga, ā, ka waikura pea i roto i te wā.

• Kowiri tira: Ka mau tonu te kanapa, te oro, me te ātaahua ki te titiro.

3. Te utu

• RinoHe iti ake te utu nā te mea he māmā ake te hanganga.

• Kowiri tiraTe utu nui ake nā te mea he chromium, he nickel, me ētahi atu huānga whakarewa.

4. Te Tiaki

• RinoMe peita, me whakakikorua, me pania rānei hei ārai i te waikura.

• Kowiri tiraHe iti noa te tiaki e hiahiatia ana, ā, he ngāwari ki te horoi.

5. Ngā tono

• RinoHe mea noa i roto i te hanga whare, te hanga waka, me ngā mīhini taumaha.

• Kowiri tiraHe mea pai mō te tukatuka kai, ngā taiao moana, me ngā ahumahi hauora.

Ngā Whakamahinga o te Rino
