Alliages de nickel Hastelloy<\/h1>\n

\n La premi\u00e8re famille d'alliages de nickel-molybd\u00e8ne-chrome con\u00e7us pour une r\u00e9sistance exceptionnelle \u00e0 la corrosion.\n Les alliages Hastelloy sont la norme pour la manipulation des produits chimiques les plus agressifs, y compris les acides forts, le chlore humide et les chlorures.\n <\/p>\n <\/div>\n\n

Hastelloy C-276<\/h3>\n

\n L'alliage de pr\u00e9dilection pour une r\u00e9sistance universelle \u00e0 la corrosion. Il r\u00e9siste mieux que tout autre alliage \u00e0 la formation de pr\u00e9cipit\u00e9s aux joints de grains, ce qui le rend adapt\u00e9 \u00e0 la plupart des applications chimiques \u00e0 l'\u00e9tat soud\u00e9.\n <\/p>\n

\n Am\u00e9lioration du C-276 avec un taux de chrome plus \u00e9lev\u00e9. Cela lui conf\u00e8re une r\u00e9sistance sup\u00e9rieure aux produits chimiques oxydants et une meilleure r\u00e9sistance globale aux piq\u00fbres localis\u00e9es et \u00e0 la corrosion caverneuse dans les environnements stagnants.\n <\/p>\n

Pourquoi choisir Hastelloy ?<\/h3>\n

\n La famille Hastelloy est d\u00e9finie par l'addition \u00e9lev\u00e9e de Molybd\u00e8ne<\/strong> (Mo). Le molybd\u00e8ne est l'\u00e9l\u00e9ment cl\u00e9 qui assure la r\u00e9sistance \u00e0 la corrosion par piq\u00fbres et par crevasses dans les environnements r\u00e9ducteurs.\n <\/p>\n

\n Lorsque les usines chimiques sont confront\u00e9es \u00e0 des conditions \"perturb\u00e9es\", o\u00f9 des m\u00e9langes d'acides, de chlorures et de solvants se produisent de mani\u00e8re impr\u00e9visible, l'Hastelloy C-276 et C-22 sont souvent les seuls mat\u00e9riaux qui survivent.\n <\/p>\n <\/div>\n\n

Why Choose Hastelloy?<\\\/h3>\\n

\\n The Hastelloy family is defined by the high addition of Molybdenum<\\\/strong> (Mo). Molybdenum is the key element that provides resistance to pitting and crevice corrosion in reducing environments.\\n <\\\/p>\\n

\\n When chemical plants deal with \\\"upset\\\" conditions\\u2014where mixtures of acids, chlorides, and solvents occur unpredictably\\u2014Hastelloy C-276 and C-22 are often the only materials that survive.\\n <\\\/p>\\n <\\\/div>\\n\\n

Hastelloy\\u00ae Nickel Alloys<\\\/h1>\\n

\\n The premier family of nickel-molybdenum-chromium alloys designed for exceptional corrosion resistance. \\n Hastelloy alloys are the standard for handling the most aggressive chemicals, including strong acids, wet chlorine, and chlorides.\\n <\\\/p>\\n <\\\/div>\\n\\n

Hastelloy C-276<\\\/h3>\\n

\\n The \\\"go-to\\\" alloy for universal corrosion resistance. It has resisted the formation of grain boundary precipitates better than any other alloy, making it suitable for most chemical process applications in the as-welded condition.\\n <\\\/p>\\n

Hastelloy C-22<\\\/h3>\\n

\\n An upgrade to C-276 with higher Chromium. This gives it superior resistance to oxidizing chemicals and better overall resistance to localized pitting and crevice corrosion in stagnant environments.\\n <\\\/p>\\n

Hastelloy B-2<\\\/h3>\\n

\\n A nickel-molybdenum alloy with significant resistance to reducing environments, specifically Hydrochloric Acid (HCl). Note: It has poor corrosion resistance to oxidizing environments.\\n <\\\/p>\\n

Hastelloy X<\\\/h3>\\n

\\n Unlike the C and B series, Hastelloy X is primarily a high-temperature alloy. It combines oxidation resistance, fabricability, and high-temperature strength, widely used in petrochemical furnaces and gas turbines.\\n <\\\/p>\\n

Why Choose Hastelloy?<\\\/h3>\\n

\\n The Hastelloy family is defined by the high addition of Molybdenum<\\\/strong> (Mo). Molybdenum is the key element that provides resistance to pitting and crevice corrosion in reducing environments.\\n <\\\/p>\\n

\\n When chemical plants deal with \\\"upset\\\" conditions\\u2014where mixtures of acids, chlorides, and solvents occur unpredictably\\u2014Hastelloy C-276 and C-22 are often the only materials that survive.\\n <\\\/p>\\n <\\\/div>\\n\\n
