4140 Flat
4140 heat treated alloy is a chromium-molybdenum, medium carbon alloy steel, and is used in a wide variety of applications requiring high strength and toughness. The chromium imparts good hardness penetration while molybdenum provides hardness uniformity and strength. In the heat treated or prehard conditions it is in the 26-32 Rockwell C range and stress relieved to minimize warping during machining. Localized hardness may also be imparted by flame or induction hardening. Primarily used in press brake dies, 4140 is also a good choice for applications requiring greater toughness than mild steel. Other typical applications include: bolts, molds, stripper plates, slides, ejector plates, jigs, fixtures, punch plates, drill collars, couplings, axle shafts, valves, machinery shafts, reamer bodies, machine stops.
