4140
An alloy responds well to heat treatment
The chromium content on 4140 provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength. In the annealed condition it machines at 110 sfm.
Other desirable properties include good wear resistance, excellent toughness, and good ductility in the quenched and tempered condition.
