WebInspection of a Jominy chart for 4140, which can be found in the SAE handbook, shows that for a Jominy distance of 5, the lower hardness limit is Rc 51 and the upper limit is Rc 59. Since the 90% martensite hardness of Rc 51 lies within the upper and lower hardness limits, the 3/4" bar will fully harden to the center. WebLSS 4140 is the classic AISI 4140 alloy steel that is sold in the annealed condition at a hardness less than or equal to 217 HBW. LSS 4142HT is a similar steel which is sold prehardened to 28 to 32 HRC (269 to 302 HBW).
