Leghe di nichel Hastelloy<\/h1>\n

\n La principale famiglia di leghe di nichel-molibdeno-cromo progettate per un'eccezionale resistenza alla corrosione.\n Le leghe Hastelloy sono lo standard per la gestione dei prodotti chimici pi\u00f9 aggressivi, compresi acidi forti, cloro umido e cloruri.\n <\/p>\n <\/div>\n\n

Hastelloy C-276<\/h3>\n

\n \u00c8 la lega di riferimento per la resistenza universale alla corrosione. Ha resistito alla formazione di precipitati ai bordi del grano meglio di qualsiasi altra lega, rendendola adatta alla maggior parte delle applicazioni di processo chimico allo stato saldato.\n <\/p>\n

Hastelloy C-22<\/h3>\n

\n Un aggiornamento del C-276 con cromo pi\u00f9 elevato. Questo gli conferisce una resistenza superiore agli agenti chimici ossidanti e una migliore resistenza complessiva alla corrosione localizzata e interstiziale in ambienti stagnanti.\n <\/p>\n

Perch\u00e9 scegliere Hastelloy?<\/h3>\n

\n La famiglia Hastelloy \u00e8 definita dall'elevata addizione di Molibdeno<\/strong> (Mo). Il molibdeno \u00e8 l'elemento chiave che garantisce la resistenza alla corrosione per vaiolatura e interstiziale in ambienti riducenti.\n <\/p>\n

\n Quando gli impianti chimici si trovano in condizioni \"anomale\", in cui le miscele di acidi, cloruri e solventi si verificano in modo imprevedibile, gli Hastelloy C-276 e C-22 sono spesso gli unici materiali che sopravvivono.\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

\\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
