- Hastelloy
Hastelloy is the registered
trademark name ofHaynes International , Inc. The trademark is applied as the prefix name of a range of twenty two different highlycorrosion -resistantmetal alloy s loosely grouped by the metallurgical industry under the material term “superalloy s” 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 XThe 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 elementsmolybdenum ,chromium ,cobalt ,iron ,copper ,manganese ,titanium ,zirconium ,aluminum ,carbon , andtungsten .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 vessel s of somenuclear reactor s,chemical reactor s, and pipes and valves in chemical industry.See also
