17-4PH u'amea u'amea

Alloy 17-4 o se chromium-copper precipitation faʻamaʻaʻaina uʻamea uʻamea lea e faʻaaogaina mo talosaga e manaʻomia ai le malosi maualuga ma se tulaga faʻafefeteina. O se tasi lea o togi fa'ama'a'aina o timuga, ona e maualuga lona malosi ma'a'a e o'o atu i le 572°F a'o fa'aalia lelei le tete'e atu i le vevela i tulaga uma e fa'afefeteina. Alloy 17-4 e lava le tete'e i le ea o le ea po'o i salt acid diluted lea e tutusa lona tete'e i le Alloy 304 po'o le 430. Alloy 17-4 e mafai ona fa'afefeteina i le vevela eseese e atiina ae ai le tele o mea totino. O ona mea fa'ainisinia e mafai ona fa'amalieina ile fa'afefe vevela lea e maua ai le malosi maualuga e o'o atu ile 180 ksi. Alloy 17-4 e le tatau ona fa'aogaina i le vevela i luga a'e o le 572°F po'o le maualalo o le vevela.

17-4 Uamea uamea
O lenei martensitic precipitation hardening stainless steel ei ai se tuufaatasiga o le maaa maualuga ma le malosi pe a uma togafitiga vevela talafeagai. E tutusa fo'i le a'a ma le vevela i le Vasega 304. O faaupuga e lua "Type 630" ma le "17-4PH" e fa'asino i le vasega tutusa.
