Features

Incoloy 890 is supplied in the annealed condition. The tensile and yield strength values of alloy 890 at ambient and elevated temperatures are approximately the same as those of alloy 803 and slightly higher than values for alloy 800HT. Like alloy 803 it is strengthened by its content of chromium and carbon. However, alloy 890 is further strengthened, especially at very high temperatures, by molybdenum and niobium.
