8620 Alloy Steel Round

8620 alloy steel is a chromium-molybdenum-nickel "triple alloy". It is a widely used case hardening alloy grade that is used where high surface hardenability and tough core is desired along with easy machinability and excellent wear resistance. The chromium and molybdenum contribute to hardness penetration while the nickel increases the toughness. Typical applications include: gauges, jigs, gears, piston rods, plastic molds, cams, pinions, spline shafts.

Finish: Cold Finished

Typical Tolerances: +0/-.008"

Applications: guages, gears, shafts, valves, collars, molds, bolts, pins
