17-4PH<\/p>\n

Norme ex\u00e9cutive : American ASTMS17400, ASTM A564 630, UNS630<\/p>\n

17-4PH est un acier inoxydable martensitique \u00e0 durcissement par pr\u00e9cipitation. En plus d’obtenir directement une structure martensitique apr\u00e8s traitement en solution solide, cet acier est encore renforc\u00e9 par un traitement de vieillissement ult\u00e9rieur – obtention d’une phase de durcissement par pr\u00e9cipitation (phase contenant du cuivre).<\/p>\n

Le 17-4PH est un acier inoxydable martensitique pr\u00e9cipit\u00e9 et tremp\u00e9 compos\u00e9 de cuivre, de niobium\/columbium. Cette nuance a une r\u00e9sistance, une duret\u00e9 (jusqu’\u00e0 300\u00b0C\/572\u00b0F) et une r\u00e9sistance \u00e0 la corrosion \u00e9lev\u00e9es. Apr\u00e8s traitement thermique, les propri\u00e9t\u00e9s m\u00e9caniques du produit sont plus parfaites et peuvent atteindre une r\u00e9sistance \u00e0 la compression aussi \u00e9lev\u00e9e que 1100-1300 mpa (160-190 ksi).<\/p>\n
