17-4 PH Pula Ho thatafatsa ho Rala ka tšepe e sa hloekang

Tlhaloso e Khutšoanyane:

Boitsebiso: 17-4 PH pula e thatafatsa tšepe e sa hloekang

Mokhoa oa tlhahiso: Ho qhibiliha le ho lahla, ho sebetsa ka chesang, ho kopanya tharollo, ho sebetsa ka mochine

Kopo: Aerospace, Lisebelisoa tsa Bongaka, Marine

Teko e fumanehang: Teko ea Mechini, Teko ea Tensile, Teko ea boima, NDT

17-4 PHke pula e thatafatsang martensiticts'epe e sa beng le mabali. E tsebahala ka matla a eona a holimo, ho thatafala, le ho hanyetsa ho hotle ho hoholo.

1. Matla a Phahameng le Thatafalo: 17-4 PH e ka fumana matla le boima bo phahameng haholo ka kalafo e thatafatsang pula, e etsa hore e lokele lits'ebetso tse hlokang matla a holimo.

2. Ho Hanela Corrosion e Ntle: Le hoja e sa khone ho bola joaloka litšepe tsa austenitic tse sa hloekang joaloka 304 le 316, e ntse e fana ka khanyetso e ntle ea kutu libakeng tse ngata.

3. Weldability e ntle: E ka chesetsoa ho sebelisoa mekhoa e fapaneng ea welding. Kalafo ea mocheso oa post-weld e khothalletsoa ho finyella thepa e nepahetseng.

4. Ho sebetsa hantle: E na le machinability e ntle boemong ba phekolo ea tharollo 'me e ka ntlafatsa ka ho eketsehileng thepa ea mochine ka mor'a phekolo ea mocheso.
