Hastelloy B3 is a high-performance alloy that provides a reliable solution for severe corrosion. Standard tuyaux en acier inoxydable et raccords de tuyauterie en acier inoxydable often lacks the needed endurance. This is especially true with reducing acids. This is where Hastelloy B3 offers a superior solution.
What is Hastelloy B3 | UNS N10675
Hastelloy B3 is a alliage à base de nickel which belongs to the Hastelloy family. It has a high nickel and molybdenum content, this gives it excellent resistance.It resists corrosion from hydrochloric acid, sulfuric acid, and phosphoric acid while exhibiting excellent thermal stability. This is especially true at high temperatures and makes Hastelloy B3 a top choice.
