Ka whakamahia e te pūnaha putanga waka he koiri maitai 409

Neke atu i te 20 tau a Xinjing e mahi ana i ngā mahi tukatuka, kaipupuri hea, me te pokapū ratonga mō ngā momo koiri, pepa me ngā pereti rino kore waikura kua hurihia matao, kua hurihia wera hoki. E 20 ngā mira hurihuri e huri ana i ā mātou rauemi kua hurihia matao, e tutuki ana i ngā paerewa o te ao, he tino tika te papatahi me ngā rahinga. Ka taea e ā mātou ratonga tapahi me te tapahi atamai te whakatutuki i ngā hiahia maha, ā, kei te wātea tonu ngā tohutohu hangarau tino pūkenga.

Ngā Huanga o te Hua

• Ko te koranu 409 he kowiri tira whānui, he chromium, he titanium kua whakapūmautia, he ferritic, ā, ko tōna whakamahinga matua ko ngā pūnaha hau putanga o ngā motuka.
• Kei roto ko te 11% chromium, koinei te nui iti rawa mō te hanganga o te kiriata mata kore e ārai ana i te waikura o te maitai kore waikura.
• He ātete pai tēnei ki te waikura i te pāmahana teitei me te kaha waenga, te ngāwari ki te hanga, me te utu whānui.
• Me whakawera wawe, ā, me mahi i ngā pāmahana whakarewa iti.
• Ka kitea pea te waikura māmā o te mata i roto i ngā taiao uaua te matū, engari he nui ake te ātete o te 409 ki ngā mahi a te maitai konumohe me ngā maitai waro.
• Kei te whakamahia whānuitia tēnei koranu i roto i ngā mahi hanga me ngā mahi hanga, i ngā wāhi e whakaaetia ana te waikura o te mata.
• He whakakapinga iti te utu ina he take te wera, engari kāore e raru te waikura e tere haere ana i te matū.
• Me whakamahana mua te maitai karaehe 409 ki te pāmahana o te 150 ki te 260°C i mua i te whakarewanga.

Tono

• Ngā huihuinga pūnaha hauātanga o ngā motuka: Ngā paipa hauātanga, ngā taupoki o ngā paipa ngāwari o te hauātanga, ngā kaitahuri whakatere, ngā ārai ahi, ngā paipa hiku
• Ngā taputapu pāmu
• Tautoko hanganga me ngā whakairi
• Ngā pouaka whakawhiti
• Ngā wāhanga o te oumu
• Ngā ngongo whakawhiti wera

Ahakoa i hangaia te Alloy 409 mō te umanga hau putanga motuka, kua whakamahia angitu i roto i ētahi atu tono ahumahi.
