Incoloy 800H is an austenitic heat resistant alloy designed for high temperature structural applications. The strength of Incoloy 800H is achieved by controlled levels of carbon, aluminum and titanium along with a 2100°F minimum anneal to achieve a grain size of ASTM 5 or coarser.
Incoloy 800H is commonly welded using RA82 (ERNiCr-3) bare wire for applications under 1450°F. RA330-04 (N08334) bare wire offers a closer match of thermal expansion coefficient, and somewhat higher strength.
