Description
 
The UNS T61206 / L6 tool steels contain 0.70% carbon with a quenched hardness of about 64 HRC. The alloying elements in these tools steels are chromium and molybdenum, and 1.50% nickel to increase toughness.

The alloy is usually produced by BEF & 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.
