T-15, available upon request, is a tungsten high-speed steel designed for use in machining operations requiring heavy cuts, high speeds and feeds.  Its primary use is in applications requiring the machining of high hardness heat-treated materials such as high temperature alloys.  The high carbon, vanadium and cobalt contents contribute to good wear resistance, hot hardness and good hardness capabilities.

T-15 is produced by the powder metallurgy process, which resulted in improved quality from the standpoint of structural uniformity, response to heat treatment, and grindability.  These factors, along with increased toughness, are increasing usage in the industry because of its recognized superior cutting ability.
