Principal Features<\/h2>\n\n\n\n

HASTELLOY\u00ae<\/sup> G-35\u00ae<\/sup> alloy (UNS N06035) was developed to resist \u201cfertilizer-grade\u201d phosphoric acid (P2<\/sub>O5<\/sub>), which is used in the production of fertilizers. Tests in real-world solutions indicate that G-35\u00ae<\/sup> alloy is far superior to other metallic materials in this acid. It was also developed to resist localized attack in the presence of chlorides, since this can be a problem beneath deposits in evaporators used to concentrate \u201cfertilizer-grade\u201d phosphoric acid. Furthermore, G-35\u00ae<\/sup> alloy is much less susceptible to chloride-induced stress corrosion cracking than the stainless steels and nickel-chromium-iron alloys traditionally used in \u201cfertilizer-grade\u201d phosphoric acid.<\/p>\n\n\n\n

As a result of its very high chromium content, G-35\u00ae<\/sup> alloy is extremely resistant to other oxidizing acids, such as nitric, and mixtures containing nitric acid. It possesses moderate resistance to reducing acids, as a result of its appreciable molybdenum content, and, unlike other nickel-chromium-molybdenum alloys, it is very resistant to \u201ccaustic de-alloying\u201d in hot sodium hydroxide.<\/p>\n\n\n\n

HASTELLOY\u00ae<\/sup> G-35\u00ae<\/sup> alloy is available in the form of plates, sheets, strips, billets, bars, wires, pipes, tubes, and covered electrodes. Applications include P2<\/sub>O5<\/sub> evaporator tubes.<\/p>\n\n\n\n
