Hastelloy is also a super alloy with slight modifications in contents. Hastelloy pipes contain nickel-molybdenum-chromium content with the addition of tungsten. Addition of tungsten helps in providing excellent corrosion resistance in a wide range of severe environments.
The high nickel and molybdenum content makes it resistant to pitting and crevice corrosion in reducing conditions. While, the chromium in these Hastelloy pipes helps in resisting oxidizing from various mediums. Carbon content in Hastelloy pipes is low, which helps in minimizing carbide precipitation during welding. Hastello
