Carbide Coarsening During Creep in 12 Percent CrMoV Steel

Carbide coarsening has been investigated in a 12 percent CrMoV steel. Studies in the gauge length (creep exposed) and in the head (stress free ageing) for both interrupted and ruptured creep specimens tested at an initial stress of 80 MPa at various temperatures and Chromium-Molybdenum or Chromium-Vanadium Steel? Sometimes Cr-Mo tools cost more than Cr-V tools and tool users want to know the reason. The difference in cost is not typically because one steel is better than the other. Because of the similar intrinsic performance capabilities of Cr-Mo and Cr-V, the higher cost of Cr-Mo tools appears to be a marketing practice thats hard to justify
