RA 602 CA Carburization 8 Extended exposure to methane (CH 4 ), carbon monoxide (CO), and other carbon rich gases can lead to carburization. As heat resistant alloys absorb carbon, their ductility will gradually decrease. Alloys that are high in nickel, such as RA 602 CA possess excellent Metal Wastage Rate (mg/cm 2 h) 1.00E-01 1.00E-02 1.00E-03 1.00E-04 1.00E-05 1.00E-06 RA600 0 2000 4000 6000 8000 10000 Exposure Time (Hours) 4 resistance to carburization attack. RA 602 CA forms a tenacious oxide scale, which provides increased protection from carburization. This protective scale impedes the carbon fro being absorbed into the base metal.

The photo at left shows a section of an RA330 fan shroud taken from a carburizing furnace displaying the pitting typical of metal dusting attack. The combination of high aluminum and chromium additions to RA 602 CA results in a resistance to metal dusting superior to alloys such as RA330, RA600, RA601, and 800HT ® alloy.
