Te whiriwhiri i te tikangā rauemi peeraKo tētahi o ngā whakataunga nui rawa atu a ngā kaihangarau i te wā e hoahoa ana i ngā mīhini pono. Ko ngā āhuatanga rauemi e whakatau ana i te pakeke, te ātete ki te waikura, te kaha kawenga, te roa o te ora o te ngenge, me te mahi whānui. E whakataurite ana tēnei tuhinga i ngā rauemi e rua e whakamahia whānuitia ana—te maitai kōromo me te maitai kore waikura—hei āwhina i ngā kaiwhakamahi ki te whiriwhiri i te kōwhiringa tika mō tā rātou tono.
Rino Kōromo (GCr15 / SAE 52100)
Ko te maitai chrome te paerewa o te ao mōngā peera maitai chrome, e tuku ana i te taurite pai o te pakeketanga, te kaha kawenga, me te whai huatanga utu. Nā te nui o te waro me te chromium ka taea te whakapakeke rawa, ka tino ātete ki te kakahu. Ka roa te ora o ēnei peera i raro i ngā kawenga taumaha, ā, he mea pai mō ngā pūnaha tuku waka, ngā motuka, ngā mīhini ahumahi, me ngā taputapu whānui. Ko te herenga matua ko te waikura: ka taea e te pānga ki te makuku, ki ngā matū, ki ngā taiao haukū rānei te whakaiti i te mahi mēnā kāore e whakamahia he hinuhinu me te hiri tika.
Kowiri tira (AISI 440C, 304)
Ka whiriwhiria te kowiri tira ina nui ake te ātete ki te waikura i te kaha kawenga mōrahi. Ngā peera kowiri tira He pai te pakeke o ngā mea i hangaia mai i te 440C, ā, he roa te ora o te ngenge, engari he ngawari ake te kowiri tira 304 engari he tino ātete ki te waikura. Ka tupu pai ēnei rauemi i roto i ngā taiao kei reira te wai, ngā kai horoi, te mamaoa, ngā matū rānei—pērā i te tukatuka kai me te inu, ngā rongoā, ngā taputapu hauora, me ngā taputapu moana. Ahakoa he nui ake te utu o ngā peera kowiri tira, ā, he iti ake te whakatauranga ngenge, he nui ake te pai o te maitai chrome i roto i ngā taiao uaua.
He aha te pakeketanga 440C ≠ Te roa o te ngenge o te maitai Chrome
Ahakoa ka taea e te maitai kore waikura 440C te eke ki ngā taumata pakeke e rite ana ki te maitai chrome, ko tōnangenge o te amoHe iti ake te roa o te ora nā ngā rerekētanga hanganga moroiti. He nui ake te chromium me ngā huānga tāpiri kei roto i te maitai kore waikura e whakapai ake ana i te ātete ki te waikura engari e whakarerekē ana i te tohatoha carbide. He iti ake te ōrite o ēnei carbide i ērā o te maitai chrome, e whakanui ana i te kukū ahotea i raro i ngā kawenga maha. Nō reira, he pai te mahi a te 440C engari kāore e taea te taurite ki te ātete ngenge roa o te GCr15/52100 kua arotauhia.
Ripanga Whakataurite Taupānga
I te wā e hanga ana i tētahikōwhiringa peera, me whakataurite e ngā kaihangarau te utu, te kaha kawenga, me ngā āhuatanga taiao.
-
Rino Kōromo (GCr15/52100):He pai rawa atu mō ngā mahi taumaha, mō te roa o te ora, ā, he iti hoki te utu.
-
Kowiri tira (440C/304):He pai rawa atu mō te makuku, ngā matū, ngā taiao kai-pai, me te pānga ki te moana.
Mā te whakamahi i ngā rauemi tika ka karohia te pakaru wawe, te waikura, me te wā kore mahi ohorere.
Ngā Otinga DEMY mō ngā Rauemi e rua
He whānuitanga katoa o ngā ratonga e tukuna ana e DEMYNgā peera DEMYi roto i te maitai kōroma me te maitai kore waikura, e kapi ana i ngā peera pōro awaawa hohonu, ngā peera porowhita, ngā peera tika, me ngā otinga hanga-rite. Ka whakaratohia e tā mātou tīma he aromatawai hangarau i runga i te kawenga, te tere, te taiao, me te roa o te oranga e tumanakohia ana kia whiwhi ai ia kiritaki i te whiringa rauemi tino pai. Ahakoa e hiahia ana koe ki te mahi ngenge tino nui, ki te tiaki waikura pai rānei, ka tukuna e DEMY te kounga pumau, teitei-tika e tautokona ana e te tiwhikete ISO/IATF16949 me te hanga matatau.
