Hastelloy Ball Valves are made from nickel-based alloys reinforced with molybdenum and chromium, together with precisely regulated levels of tungsten, iron, and cobalt, based on the particular grade. This distinctive makeup delivers exceptional resistance to corrosion, pitting, and crevice attack in extremely harsh chemical settings. From a mechanical standpoint, Hastelloy offers high tensile strength, remarkable hardness, and stability even at high temperatures. The alloy stays tough under thermal cycling and high-pressure situations. Its durability, fatigue resistance, and dimensional stability make Hastelloy Ball Valves ideal for enduring performance in challenging industrial applications.
