Ko te 17-7PH he austenitic-martensitic precipitation whakapakeke kowiri tira i whakawhanakehia i runga i te kaupapa o 18-8CrNi, e mohiotia ana ano ko te huringa wahanga whakahaere he kowiri tira. te hanganga martensitic waro i te wa e whakamahana ana ki te pāmahana rūma.Ko tenei huringa kaore e oti kia taka ra ano te mahana ki te 90°F.Ko te whakamahana i muri mai ki te mahana o te 900-1150°F mo te kotahi ki te wha haora ka kaha te rerenga o te ua.Ko tenei maimoatanga whakapakeke ka whakapataritari i te hanganga martensitic, ka piki ake te ngawari me te uaua
