The development of alloys for use in pyrolysis furnace radiant coils beginning with HK-40 through Manaurite XA are described. Laboratory testing for carburization resistance were conducted using a new exposure technique. The test results indicate that increasing nickel content and the addition of elements such as Nb and W improve the carburization resistance of both the basic (Fe, Ni, Cr) alloys and Manaurite XA. The importance of a stable internal oxide layer on carburization resistance of these alloy systems is also covered.
