The most-used names for this grade.About Nickel and cobalt alloys
Nickel and cobalt alloys are metallic materials whose properties are developed through nickel-, cobalt-, or combined alloying systems. They are characterised by strong resistance to corrosion, oxidation, wear, and loss of strength at elevated temperatures, making them suitable for turbine components, chemical-processing equipment, and other demanding high-temperature applications.
This describes the material class as a whole. Always confirm the individual grade against the standard before ordering.

Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade.

The scale is logarithmic, not the element’s raw share of the alloy — the only honest way to fit 0.01 % and 100 % in one picture, and it means every value here can be compared with every other.

Predicted transformation temperatures
Not enough recorded composition to predict a transformation temperature for this grade — missing: Ni, Mo.
Physical & mechanical properties
An absent property means we hold no value for it — it is left out rather than estimated, interpolated from a neighbouring grade, or filled from a handbook. It does not mean the property is undefined for the material.
Similar grades — and why
Selection rule, stated so you can disagree with it: same number class 2.4, a shared category, and a published range for Ni / Cr that overlaps this grade’s. These are neighbours in composition space — they are not equivalents, and none is claimed to be interchangeable with this grade.
