    \u00a0 \u00a0 \u00a0 L'alliage SUS630 est un acier inoxydable martensitique pr\u00e9cipit\u00e9 et durci, compos\u00e9 de cuivre, de niobium et de cinabre. Nuance correspondante : 0Cr17Ni4Cu4Nb 05Cr17Ni4Cu4Nb S17400<\/span><\/p>\n

    \u00a0 \u00a0 \u00a0 Le SUS630 est un acier inoxydable durci \u00e0 pr\u00e9cipitation de martensite qui pr\u00e9sente une r\u00e9sistance \u00e9lev\u00e9e, une grande duret\u00e9, de bonnes performances de soudage et une bonne r\u00e9sistance \u00e0 la corrosion. Il a \u00e9t\u00e9 largement promu et utilis\u00e9 dans les vannes, les arbres, les fibres chimiques, l'a\u00e9rospatiale et d'autres industries, et a des composants \u00e0 haute r\u00e9sistance avec certaines exigences de r\u00e9sistance \u00e0 la corrosion.<\/span><\/p>\n

          • L'alliage SUS630 pr\u00e9sente une r\u00e9sistance \u00e0 la corrosion sup\u00e9rieure \u00e0 celle de toute autre plaque d'acier inoxydable trempable standard. Dans la plupart des cas, sa r\u00e9sistance \u00e0 la corrosion n'est pas inf\u00e9rieure \u00e0 celle de 304.<\/span><\/li>\n

              L'alliage SUS630 est un acier inoxydable martensitique pr\u00e9cipit\u00e9 et tremp\u00e9, et cette nuance pr\u00e9sente une r\u00e9sistance m\u00e9canique, une duret\u00e9 et une r\u00e9sistance \u00e0 la corrosion \u00e9lev\u00e9es. Apr\u00e8s traitement thermique, les propri\u00e9t\u00e9s m\u00e9caniques du produit sont plus parfaites, atteignant une r\u00e9sistance \u00e0 la compression allant jusqu'\u00e0 1100-1300 mpa (160-190 ksi). Cette qualit\u00e9 ne peut pas \u00eatre utilis\u00e9e \u00e0 des temp\u00e9ratures sup\u00e9rieures \u00e0 300\u00b0C (570F) ou tr\u00e8s basses. Elle pr\u00e9sente une bonne r\u00e9sistance \u00e0 la corrosion dans l'atmosph\u00e8re et aux acides ou sels dilu\u00e9s, et sa r\u00e9sistance \u00e0 la corrosion est la m\u00eame que celle des nuances 304 et 430.<\/span><\/p>\n
