Hastelloy B3 is a high-performance alloy that provides a reliable solution for severe corrosion. Standard tubos de acero inoxidable y accesorios de tubería de acero inoxidable 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 aleación a base de níquel 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.
Key Advantages of Hastelloy B3
Hastelloy B3 is very strong. It resists non-oxidizing acids and handles hydrochloric and sulfuric acids well.
It is stable under heat. It resists sensitization. This means its corrosion resistance stays strong after welding. This is a key feature for fabricated systems.
This alloy is easy to form. It can be readily welded. This is crucial for complex fabrications. It ensures strong, reliable joints for piping systems.
Previene agrietamiento por corrosión bajo tensión en entornos difíciles. This is vital in chloride-rich solutions. It ensures system integrity under stress.
