Cr12MoV is not the AISI D2 equivalent. The GB grade that matches D2, 1.2379 and SKD11 is Cr12Mo1V1, which carries more vanadium. Compared with D2, Cr12MoV holds less molybdenum and vanadium, so it costs less while keeping the chromium carbide wear resistance of the Cr12 family. Where a drawing specifies D2, 1.2379 or SKD11, order Cr12Mo1V1 or D2. Where it specifies Cr12MoV, this grade ships annealed as round bar, flat bar, plate or forged block.
