FEATURE:

By virtue of its chromium and silicon contents, alloy 890 offers the greatest resistance to attack at elevated temperatures of any of the INCOLOY family of alloys.

Alloy 890 out-performs even alloy 803, which is well known for its resistance to attack in carburizing environments.

Again, alloy 890 offers significantly superior performance.


APPLICATION:

Mainly used for domestic and industrial sheathed heater applications and other high-temperature applications.
