UNS T13110 / M10 high-speed steel is a molybdenum-based high-speed tool steel in American standards, and the grade of M10 steel is Mo8Cr4V2 steel. The main alloying element of molybdenum high-speed tool steel is molybdenum, which does not contain tungsten or contains a small amount of tungsten. Its main characteristics are fine carbide particles, uniform distribution, good toughness, but high decarburization sensitivity and overheat sensitivity, and a narrow range of hot processing and heat treatment.

The alloy is usually produced by EAF & AOD followed by electroslag remelting (ESR) / VAR if necessary for special purpose.
Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' requirements.
100% Ultrasonic test ASTM E2375 /SAE AMS 2154 /SEP 1923 /GB/T 4162 /EN 10228-3.
Bars are usually supplied black/bright in the annealed condition.
