Comparative Sulfidation Resistance

Independent outside testing laboratories have also verified the superior performance of HR-120® alloy in sulfidizing environments. Petten Establishment in the Netherlands found that HR-120® alloy performed significantly better than alloys 800H, 347SS and 321SS at 1290°F (700°C) in hydrogen plus 7 percent carbon monoxide plus 1.5 percent water vapor plus 0.6 percent hydrogen sulfide. The HR-120® alloy was found to be magnitudes better than the other alloys.
