Alloy 4140 (AISI 4140) is one of the most popular direct hardening Cr-Mo alloy steel plates that have the ability to develop an extensive range of hardness and strength. Alloying elements and thermal treatments, such as quenching and tempering, greatly influence the hardness and strength of the steel.
4140 is an alloy steel that is supplied in either the annealed or prehardened condition. The prehardened condition is heat treated to a medium hardness (HRC 28/32) and is designated as 4140 HT. 4140 annealed is supplied in the soft condition and can be hardened to RC 54. 4140 annealed is designated as 4140 Ann or simply 4140. 4140 HT is supplied in many forms such as hot rolled or turned 4140 Annealed Cold Rolled Round Bar Coremark Metals4140 cold rolled round bars are an excellent candidate for most processing techniques. 4140 annealed cold roll bars is a high strength and abrasion resistant alloy. Extreme size accuracy, straightness and concentricity combine to minimize wear in high speed applications. Commonly used in gears, shafts, axles, bolts, studs and machine parts.
