Hastelloy -- material overview

Looking for a valve in this exotic alloy? Find it in the following configurations: Ball, Butterfly, Cast, Check, Control, Cryogenic, Custom made, Foot, Forged, Gate, Globe, Needle, Plug, and Safety relief, as well as Strainers.

The Alloy Valve Stockist supplies hastelloy gate, globe, check, ball, butterfly, plug, needle and custom made valves.

As a valve stockist, we stock, supply and distribute valves in exotic materials such as titanium, hastelloy, duplex, super duplex, monel, incoloy, inconel, alloy 20, 254 SMO, 6 Moly,tantalum, zirconium, uranus, 904L both in stock and can also deliver against tight lead times.

Hastelloy is the registered trademark name of Haynes International, Inc. The trademark is applied as the prefix name of a range of twenty two different highly corrosion-resistant metal alloys loosely grouped by the metallurgical industry under the material term "superalloys" or "high-performance alloys".

The predominant alloying ingredient is typically the transition metal nickel. Other alloying ingredients are added to nickel in each of the subcategories of this trademark designation and include varying percentages of the elements molybdenum, chromium, cobalt, iron, copper, manganese, titanium, zirconium, aluminum, carbon, and tungsten.

The primary function of the Hastelloy super alloys is that of effective survival under high-temperature, high-stress service in a moderately to severely corrosive, and/or erosion prone environment where more common and less expensive iron-based alloys would fail, including the pressure vessels of some nuclear reactors, chemical reactors, and pipes and valves in chemical industry.

The most common Hastelloy alloys are Hastelloy B, Hastelloy B2, Hastelloy B3, Hastelloy C, Hastelloy C22 and Hastelloy C276.
