Stocked in standard Fractional, .005" Oversize, Letter Size, and Metric Diameters, Royal Knightride® Hotwork Ejector Pins are precision crafted from the finest grade of H-13 thermal shock resistant Hotwork Die Steel. The core is hardened throughout to 41-45 Rc and the surface is ion nitrided to 65-74 Rc in a proprietary process, designed to create a diffusion layer between the nitrided case and the hardened core. This process produces the ideal combination of toughness and long life and also prevents surface nicking and flaking which may be a problem with other nitrided pins. The diameters are precision ground to a high surface finish (5-10RMS) and tight tolerance (.0003") which reduces friction and increases pin life. For additional technical specifications and pricing, please refer to the RX Knightride Ejector Pins pages of the online catalog.
