Acciaio Inox 17-4PH



Acciaio Inox 17-4PH

L’ acciaio inox 17-4 è caratterizzato da elevate proprietà meccaniche e da un’ottima resistenza alla corrosione.
Questo materiale è ideale per la costruzione di accessori per la produzione (DirectPart) come prototipi funzionali in metallo, produzione di piccole serie, prodotti personalizzati o pezzi di ricambio. I componenti costruiti in acciaio inox 17-4 possono essere lavorati tramite saldatura, sottoposti a processo di elettroerosione a filo, micropallinatura ed essere lucidati se richiesto.
