ABSTRACT:
The method of making steel with carbide banding entails using steel with undissolved carbides distributed within the steel for forming steel with carbide banding, wherein the steel is about 0.3 weight percent to about 2.2 weight percent carbon and at least 0.003 weight percent of chromium, molybdenum, aluminum, vanadium, tungsten, or a similar carbide forming element; then, deforming the steel with undissolved carbides to create steel with carbide banding upon cooling, heating the steel with undissolved carbides for a specified time ranging at a specified temperature to form an austenitic steel with undissolved carbides, and cooling the austenitic steel with undissolved carbides to maintain the undissolved carbides within a crystalline matrix forming steel with carbide banding.
