17-4PH ANNEALED SHIPI E SEBELE

Alloy 17-4 ke chromium-copper precipitation e thatafatsa tšepe e sa hloekang e sebelisoang bakeng sa lits'ebetso tse hlokang matla a phahameng le boemo bo itekanetseng ba ho hanyetsa kutu. Ke e 'ngoe ea limaraka tse thatafatsang pula, kaha e na le matla a phahameng a thata ho fihla ho 572 ° F ha e ntse e bontša khanyetso e ntle ea kutu maemong ohle a phekoloang ke mocheso. Alloy 17-4 e na le ho hanyetsa ka ho lekaneng ho senya sepakapaka kapa ka letsoai la diluted acid moo ho hanyetsa ha eona ho lekanang le Alloy 304 kapa 430. Alloy 17-4 e ka phekoloa mocheso ho mefuta e fapaneng ea mocheso ho hlahisa mefuta e mengata ea thepa. Thepa ea eona ea mochini e ka ntlafatsoa ka kalafo ea mocheso moo matla a chai a phahameng haholo a fihlang ho 180 ksi a ka finyelloang. Alloy 17-4 ha ea lokela ho sebelisoa ka mocheso o ka holimo ho 572 ° F kapa mocheso o tlaase haholo.

17-4 Ts'epi e sa hloekang
Moputso ona oa martensitic o thatafatsang tšepe e sa hloekang o na le motsoako oa ho thatafala ho phahameng le matla ka mor'a phekolo e loketseng ea mocheso. E boetse e na le kutu le mocheso o ts'oanang le Kereiti ea 304. Mantsoe a mabeli "Mofuta oa 630" le "17-4PH" a bolela kereiti e tšoanang.
