Yield strengths range from 110 ksi through 140 ksi, but we can temper it to other strength levels. When compared with standard 4140 heat treated to the same tensile and yield strengths, 4140HW achieves significantly higher toughness, as measured by impact strength (see Figure 9). 4140HW combines medium carbon content with high-end chromium,
Chuck_Steak. A properly quenched and tempered alloy steel should have a yield to tensile strength ratio of greater than 90%. It looks like your connecting rod is closer to 50%; I'd say your quench severity needs to be increased to assure that you are getting a fully martensitic microstructure.

AISI 4130 steel alloy is used primarily in the construction of commercial and military aircraft and ground support systems. Alloy steel 4130 is an intermediate strength material. Lighter gauges offer lighter weight but still maintain great strength, making it excellent for auto racing and aerospace.
HIGH TENSILE STEEL AISI 4140 AISI 4140 Chrome - Moly High Tensile Steel, generally supplied hardened and. tempered to Condition T in sections. up to 100mm, with a tensile strength of 850 1000 MPa and aiming for this strength range in larger sections. It offers a very good balance of strength, toughness and wear-resistance.
AISI 4140 is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. AISI 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness.

Both SAE-AISI 4140 steel and SAE-AISI D2 steel are iron alloys. They have 86% of their average alloy composition in common. There are 29 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.
4140 alloy steel is typically normalized at 870 C (1600), and should be cooled at a specified temperature in still air. Spheroidizing Annealing For spheroidizing annealing of 4140 alloy steel, it needs heat treated to 749 C (1380 F), followed by slowly cooling to 666 C (1230 F) at a rate of 6 C (10 F)/hour, or rapid cooling to 675 C for isothermal annealing.
