There are many different grades of Hastelloy, many of which are nickel-chromium-molybdenum alloys. Each of these grades has been optimized for a specific purpose, but all of them are highly resistant to corrosion. The Corrosion-Resistant HASTELLOY alloys are widely used by the chemical processing industries. The need for reliable performance leads to their acceptance and growth in the areas of energy, health, and environmental, oil and gas, pharmaceutical, and flue gas desulfurization industries.
- [Monel Ball Valves](https://jstvalve.com/product/monel-ball-valves/): The monel ball valves are designed to provide years of service at an economical cost and are available in various options. It with owns higher corrosion resistance than copper-based alloys in flowing seawater. Monel ball valves are suitable for transporting of high temperature hydrogen fluoride gas and hydrofluoric acid solution.
