... on them, and forging dies have hot steel rubbing on them. The H steels do not get very hard at 43 to 53 HRC. So, to prevent galling and adhesive wear, ejector pins and cores are often nitrided. Thus, a 53 HRC mold with 60 HRC core pins (nitrided H13) reasonably resists adhesive wear. Forging dies...
