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