He aha te rerekētanga i waenga i te 17-4PH me ētahi atu maitai whakapakeke-tau (PH)?

He aha te rerekētanga i waenga i te 17-4PH me ētahi atu maitai whakapakeke-tau (PH)?

Kupu Whakataki

Ko ngā maitai kore waikura whakapakeke-taumaha (ngā maitai PH) he momo koranu ātete-waikura e whakakotahi ana i te kaha o ngā maitai martensitic me te austenitic me te ātete-waikura tino pai. I roto i ēnei,17-4PH maitai kore waikuraKoinei pea te mea e whakamahia whānuitia ana nā ōna āhuatanga miihini tino pai me te ngāwari o te hanga. Engari me pēhea te whakataurite ki ētahi atu momo PH pēnei i te 15-5PH, 13-8Mo, 17-7PH, me te Custom 465? Ka ruku hohonu tēnei tuhinga ki ngā rerekētanga o te hanganga, te maimoatanga wera, ngā āhuatanga miihini, te ātete ki te waikura, me ngā whakamahinga.

He Tirohanga Whānui mō ngā Rino Kowiri tira e Whakapakari ana i te Ua

Ka whiwhi te pakari o ngā maitai whakapakeke-ua i te hanganga o ngā matūriki iti i roto i te anga maitai i te wā e whakamahanahia ana. E toru ngā wāhanga matua o ēnei maitai:

1. Ngā maitai PH Martensitic(hei tauira,17-4PH(15-5PH)
2. Ngā maitai PH haurua-austenitic(hei tauira, 17-7PH)
3. Ngā maitai PH Austenitic(hei tauira, A286)

Whakarāpopototanga

Whakamutunga

Ahakoa ko te 17-4PH tonu te maitai kore waikura PH rongonui mō ngā mahi whānui, he rerekē ngā painga o ia momo PH rerekē, ā, he pai ake mō ngā whakaritenga motuhake. Mā te mārama ki ngā āhuatanga rerekē o ēnei koranu ka taea e ngā kaihanga rauemi me ngā kaihoko te whakatau whai whakaaro i runga i te kaha, te pakari, te ātete ki te waikura, me te utu.
