Piston pins perform reliably under the loads and stresses of their environment and feature: Strength and rigidity Durability and a high fatigue threshold Light weight to keep inertia forces to a minimum Superior surface finish for good bearing properties within the piston assembly Cost-effective production Materials used in Federal-Mogul Powertrain piston pins include: AE308 Boron steel for medium- and heavy-duty diesel applications AE527 Chromium steel for cold-extruded gasoline pins AE530 1 percent Chromium steel for cold-extruded diesel pins Piston pin fit and clearance must be carefully optimized and controlled to avoid noise and excessive axial movement at one extreme, and scuffing at the other. Federal-Mogul manufactures pins by creating an extruded blank with a finished internal form rather than machining from solid bar. This process reduces waste and gives a high-quality, consistent and internal form. Piston pins are case-hardened, which involves carburizing, heat treatment and tempering to increase wear-resistance, strength and fatigue strength
