Abstract:
1. 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: b. deforming the steel with undissolved carbides; c. removing a portion of the steel with undissolved carbides; d. heating the steel with undissolved carbides for a time ranging from about 5 minutes to about 12 hours at a temperature ranging from about an A-sub 1 temperature to about 50 degrees Fahrenheit above an A-sub 3 temperature, forming an austenitic steel with undissolved carbides; and e. cooling the austentitic steel with undissolved carbides to maintain the undissolved carbides within a crystalline matrix forming steel with carbide banding.
