ABSTRACT:
A product resistant or immune to carburization, metal dusting, coking, oxidation, and having sufficient mechanical strength for use at temperatures greater than 400° C. The product consists of a load-bearing member and a corrosion resistant member, wherein the corrosion resistant member is a Cu—Al-alloy comprising Si. The product can be used in CO-containing atmospheres, and/or hydrocarbon containing atmospheres or solid carbon containing processes. A method of resisting carburization, metal dusting, coking and oxidation is also disclosed.
