METAL DUSTING IN A LABORATORY ENVIRONMENT ALLOYING ADDITION EFFECTSB. A. BAKER, Special Metals Corporation, Huntington, West VirginiaG. D. SMITH, Special Metals Corporation, Huntington, West VirginiaABSTRACTLong-term testing of a wide variety of nickel-base and iron-base alloys has beenconducted in an ENVIRONMENT generated by an inlet gas composition of CO-20%H2 at 621 C. Some degree of METAL DUSTING attack has been observed for allalloys tested. Multivariate analysis has been performed, in order to determine theeffects of various alloying additions upon the mass loss rate and the pittingprogression rate. The results indicate the beneficial effects of a nickel-base alloymatrix, scale-forming element additions, and the presence of certain carbide-forming elements upon alloy METAL DUSTING has been responsible for considerable losses in equipment and production timeacross numerous industries including petrochemical processing, direct iron-ore reduction andheat treating.
The results indicate the beneficial effects of a nickel-base alloy matrix, scale-forming element additions, and the presence of certain carbide- forming elements upon alloy performance.
