Principal Design Features: A Ni-Cr-Fe alloy that resists high temperature oxidation. This alloy is a first choice for an upgrade from the 300 series stainless steels when improved performance or strength at temperature is required. For higher ASME Boiler and Pressure Code design values, consider Alloy 800HT.

Partial List of Applications: Heat treating equipment and fixtures. Sheathing for electric resistance alloy tubular heating elements. Heat exchangers.
