RoyAlloy is a new stainless mold-base steel, developed by Edro Specialty Steels, to overcome shortcomings associated with prehardened 420F (1.2085) stainless holder steels: a lack of toughness, unpredictable stability, inconsistent machinability and poor weldability. Edro says thermal treatments give the material improved dimensional stability after machining without the need for stress relieving. RoyAlloy is a 400 series martensitic stainless designed specifically for plastic and rubber tooling. It's available from stock in flat sizes up to 12 inches thick and rounds up to 12 inches in diameter. For more information, go to
