Hastelloy Nickel-alloy Chemical Composition, Grade Chart, Tables and Documents

Hastelloy is a versatile alloy made of nickel and known for its remarkable resistiveness concerning corrosion in several chemical, aerospace, and marine applications. Its chemical makeup may vary depending on the ratio of nickel, chromium, molybdenum, and other (e.g., cobalt, tungsten or iron) elements which may give it unique properties, such as high temperature strength, oxidation resistance, and pitting or crevice corrosion resistance. Hastelloy family has graped its name with different grades, among them C-276, C-22, and X which proves their wide usage in different applications. Grade charts, tables, and documents that provide a multitude of details on regarding the each grade composition, chemical compositions, mechanical properties as well as application recommendations help engineers and material specifiers select suitable alloy out of the grade range presenting their specific requirements.

Hastelloy Nickel-alloy Chemical Composition Table

Hastelloy is known to be the high-performance nickel type brand finds fame in providing supreme performance under the toughest conditions. Without the appropriate chemical composition, its usefulness is unlikely to be expected. Most often, Hastelloy alloys sorts out nickel and chromium as the major elements and they may have molybdenum, cobalt, iron, and tungsten statically. Another notable example comprising nickel, molybdenum, chromium and other smaller amounts of elements is Hastelloy C276. The specific composition is determined by the type of paint grade and the performance that it offers. This variety of compositions enables Hastelloy alloys to withstand the corrosive atmosphere in chemical processing, aerospace, marine, and other industries. As a result, these alloys are irreplaceable in many mission-critical applications.
