Hastelloy G50 was engineered when a process involves aggressive chemicals, material selection becomes a strategic defense.Standard tubos de aço inoxidável e conexões para tubos de aço inoxidável simply cannot withstand the attack. This is especially true with hot sulfuric acid. Hastelloy G50 is a purpose-built solution. Its specific properties are what make it so reliable.
What is Hastelloy G50 | UNS N06950
Hastelloy G50 is a type of liga à base de níquel. It is a member of the Hastelloy family. Its composition is nickel, cromo, molibdênio and iron. This blend provides amazing corrosion resistance. It is particularly effective against strong reducing and oxidizing acids. It’s the material you use when other stainless steel and nickel alloys just don’t have enough endurance.
Key Advantages of Hastelloy G50
Hastelloy G50 is built to resist non-oxidizing acids. It’s a champion against high-temperature sulfuric acid.
The alloy has excellent resistance to corrosão e corrosão em fendas. These are common forms of attack.
This alloy is stable under heat. Its corrosion resistance stays strong after welding. This means your pipes and fittings stay strong.
Hastelloy G50 is excellent at resisting rachaduras por corrosão sob tensão. This type of failure forms tiny cracks.
