HS6-5-3

1.3344 (HS6-5-3) is a [[glossary:schnellarbeitsstahl|high-speed steel]] with 6 % [[element:W|tungsten]], 5 % [[element:Mo|molybdenum]], and 3 % [[element:V|vanadium]]. The higher vanadium content creates more and harder carbides — better wear resistance than HS6-5-2. Used for tools for abrasive materials, hard machining.
