Nominal weight %. Source: Crucible datasheet (Niagara Specialty Metals). What the alloying adds: vanadium (4%) gives hard vanadium carbides, the main source of wear resistance; niobium (2%) gives very hard, fine niobium carbides; nitrogen (0.2%) gives hardness without tying up chromium, which helps rust resistance.
