The influence of carburization test methods upon the extent of carburization of cast, heat resistant, austenitic alloys has been examined. The test environments used to carburize the alloys simulated aspects of the conditions present in ethylene furnaces. The extent of carburization varied with the test environment used. Testing also showed that stress rupture results of alloys exposed to identical carburization conditions were influenced by the carburization and differed from results for non-carburized alloys.
