17-4PH Rawa Rawa

Ko te 17-4PH he chromium-nickel-copper precipitation whakapakeke martensitic kowiri tira.Ko tenei karaehe o te kowiri tira he taonga penei i te kaha teitei, te pakeke me te aukati waikura.I muri i te maimoatanga o te wera, he pai ake nga ahuatanga miihini o te hua, a, ka taea e te kaha o te pupuhi te eke ki te 1100-1300MPa (160-190ksi).Kare e taea te whakamahi i tenei karaehe i te pāmahana teitei ake i te 300°C (572°F) he iti rawa ranei.He pai te waikura ki te hau me te waimeha waikawa, tote ranei.Ko tona parenga waikura he rite ki te 304. Magnetic.
