Title (EN) GRAIN BOUNDARY COHESION ENHANCED SULFIDE STRESS CRACKING (SSC)-RESISTANT STEEL ALLOYS
(FR) ALLIAGES D'ACIER RÉSISTANTS AUX FISSURES SOUS CONTRAINTE INDUITE PAR SULFURE ET À COHÉSION RENFORCÉE ENTRE LES GRAINS
Abstract:
(EN) Alloys, processes for preparing the alloys, and articles including the alloys are provided. The alloys can include, by weight, about 0% to about 8% nickel, about 1% to about 6% tungsten, about 1% to about 4% copper, about 0.1% to about 2% chromium, about 0.01% to about 1% vanadium, about 0.01% to about 0.5% carbon, about 0.01% to about 0.1% titanium, about 0.001% to about 0.01% boron, about 0% to about 1% silicon, and about 0% to about 0.1% calcium, the balance essentially iron and incidental elements and impurities.
(FR) La présente invention concerne des alliages, des procédés de préparation des alliages, et des articles contenant les alliages. Les alliages peuvent comprendre, en poids, environ 0 % à environ 8 % de nickel, environ 1 % à environ 6 % de tungstène, environ 1 % à environ 4 % de cuivre, environ 0,1 % à environ 2 % de chrome, environ 0,01 % à environ 1 % de vanadium, environ 0,01 % à environ 0,5 % de carbone, environ 0,01 % à environ 0,1 % de titane, environ 0,001 % à environ 0,1 % de bore, environ 0 % à environ 1 % de silicium et environ 0 % à environ 0,1 % de calcium, le reste étant essentiellement du fer et des éléments et des impuretés fortuits.
