Abstract
In a method for manufacturing a forging die with improved wear resistance, hot-work tool steel is obtained in which Al is added as a de-oxidizing agent during manufacture of the hot-work tool steel in a sufficient quantity such that it is only partially consumed during the de-oxidizing process, leaving Al in a range of greater than 0.015 weight percent after the de-oxidizing process. The forging die is shaped from the hot-work tool steel. By a subsequent nitriding process, a hardened surface is created on the forging die by heating in a nitriding atmosphere by interaction with the Al to improve a hardened surface on the hot-work forging die resulting in an improvement in wear resistance.
