Patent ID: 7459039

Claim:
A method of making steel with carbide banding comprising the steps of: a. obtaining steel with undissolved carbides distributed within the steel for forming steel with carbide banding, wherein the steel comprises: i. from about 0.3 weight percent to about 2.2 weight percent carbon; and ii. at least about 0.003 weight percent of a metal selected from the group consisting of chromium, molybdenum, aluminum, vanadium, or tungsten; b. deforming the steel with undissolved carbides to create steel with carbide banding upon cooling; c. heating the steel with undissolved carbides for a time ranging from about 5 minutes to about 12 hours at a temperature above an A-sub 1 temperature to form an austenitic steel with undissolved carbides; and d. cooling the austenitic steel with undissolved carbides to maintain the undissolved carbides within a crystalline matrix forming steel with carbide banding.
