Hastelloy B3 Round Bar UNS N10675
Manufacturer and exporter of Hastelloy B3 Round Bar UNS N10675 in China.
What is Hastelloy B3?
Alloy B-3® is a nickel-molybdenum solid solution strengthened super-alloy with a nominal chemical composition of 65% nickel and 28% molybdenum with additions of iron, manganese, tungsten, and cobalt. It is commonly referred to by the tradename Hastelloy® B-3 and the universal designation UNS N10675. B-3® is known for its resistance to reducing acids, particularly hydrochloric and sulfuric, and also has good thermal stability.
The Hastelloy B3 Round Bar is a nickel-molybdenum alloy engineered to deliver unmatched resistance to hydrochloric acid, sulfuric acid, and other aggressive chemical environments. Renowned for its thermal stability, low ductility loss, and exceptional stress corrosion cracking resistance.
