Alloy Steel 8620
Grade Summary: Nickel imparts good toughness and ductility, chromium and molybdenum contribute increased hardness penetration and wear. They are readily carburized and the well-balanced alloy content permits hardening to produce a strong, tough core and high case hardness.
Typical Applications: Because of the fine combination of properties that may be developed, as well as the ease with which it may be processed, this material is ideal for a wide variety of applications. Gears, pinions, oil pump piston rods and liners, spline shafts, piston pins, cams, jigs, plastic molds, oil tool slips, jaws, gauges,etc.
Available products: Round Bar and Plate
