Hastelloy G35 is a big deal in tough situations. When you need a material that can handle seriously harsh acids, you can’t rely on standard tubos de aço inoxidável e conexões para tubos de aço inoxidável. That’s a recipe for disaster. Instead, you turn to something like Hastelloy G35. Its unique properties are what make it so reliable.
What is Hastelloy G35 | UNS N06035
Hastelloy G35 is liga à base de níquel,which belongs to hastelloy family. It’s an alloy of nickel, cromoe molibdênio. This combination gives it incredible power. It can fight off strong acids like hydrochloric and sulfuric acid. What’s more, it’s super stable. This means its properties don’t change much, even when it gets hot. That’s a huge plus. It makes Hastelloy G35 a top pick for jobs where other materials just give up.
Key Advantages of Hastelloy G35
Hastelloy G35 is built to resist non-oxidizing acids. It’s a champion against hydrochloric acid. It also stands up to sulfuric acid.
This alloy doesn’t change easily. The heat from welding won’t mess up its corrosion resistance. This means your pipes and fittings stay strong.
For such a tough material, it’s surprisingly easy to fabricate. You can form it and weld it without major issues.
Hastelloy G35 is excellent at resisting rachaduras por corrosão sob tensão. This is a type of failure where tiny cracks form and grow.
