Hastelloy

Hastelloy

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”.

Examples of Hastelloy alloys are:
* Hastelloy A
* Hastelloy B
* Hastelloy B2
* Hastelloy B3
* Hastelloy C
* Hastelloy C4
* Hastelloy C22
* Hastelloy C2000
* Hastelloy C263
* Hastelloy C276
* Hastelloy D
* Hastelloy G
* Hastelloy G2
* Hastelloy G3
* Hastelloy G30
* Hastelloy G50
* Hastelloy H9M
* Hastelloy N
* Hastelloy R235
* Hastelloy S
* Hastelloy W
* Hastelloy X

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.
