The following datasheet gives an overview of AISI 4140 alloy steel. 4140 alloy steel material is ahighquality Quenched and Tempered Alloy Structural steel, Itbelong to the high quality medium carbon alloy steel, Oil Quenched & Tempered Hardenss is 28-34 HRC.4140 Annealing delivery hardenss less than 250HB.
Tempering temperature of 4140 alloy steel can be from 204-649 C (400-1200F) after normalizing and oil quenching, and the corresponding Rockwell hardness can be obtained. Forging Material 4140 forging temperature is about 1232 C (2250 F).
quenching of AISI 4140 steel C-rings in oil and water. The severity of the water quenching was responsible for the larger distortion when compared to the oil water quenching process. The simulations are carried out with coupled analysis of heat transfer, deformation mechanics and phase transformations. In addition,
Quenched and tempered SAE-AISI 4140 is SAE-AISI 4140 steel in the quenched and tempered condition. It has the highest strength compared to the other variants of SAE-AISI 4140 steel. The graph bars on the material properties cards below compare quenched and tempered SAE-AISI 4140 to: SAE-AISI wrought steels (top), all iron alloys (middle), and the entire database (bottom).
AISI 4140 alloy steel is heated at 845C (1550F) followed by quenching in oil. Before hardening, it can be normalized by heating it at 913C (1675F) for a long period of time, followed by air cooling.
ASTM 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness. The desirable properties of the AISI steel 4140 include superior toughness, good ductility and good wear resistance in the quenched and tempered condition.
Don, Normally 4140 is an oil quench steel. In a section this large you cannot blow enough air to make difference. You might get away with a water mist spray. Carburizing also requires a quench to be hard and is VERY shallow, insufficient for an anvil.
Smaller sections of 4140 might be quenched in oil, heavier sections in water. Tempering is carried out to relieve stresses from the hardening process, but primarily to obtain the required mechanical properties.
4140 steel is a low alloy steel commonly used in structural members and mechanical components. It is composed of Chromium, Manganese, Carbon, Silicon, Molybdenum, Sulfur and Phosphorus submerged in a matrix of Iron.
The desirable properties of the AISI 4140 include superior toughness, good ductility and good wear resistance in the quenched and tempered condition. The AISI 4140 cold finished annealed chromium-molybdenun alloy steel can be heated using various methods to yield a wide range of properties, hence it is often used as stock for forging as it has self-scaling properties.

AISI 4140 PREHARD HEAT TREATED MATERIAL OR ANNEALED. IN STOCK FOR IMMEDIATE SHIPMENT. 4140 Chromium-Molybdenum Steel. Supplied in the annealed or prehardened condition. 4140 PREHARD 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 40.
The Hardness of the 4140 Quenched and Tempered steel (It #69) was taken as the average of three randomly chosen fatigue specimens and is given in Appendix 1. The individual hardness measurements are also given in
TimkenSteels 4140HW grade is a fine-grained, low-alloy steel that offers optimum heat-treat response in heavier cross-sections. You find 4140HW in a variety of bar and tubing applications in quenched and tempered conditions. Yield strengths range from 110 ksi through 140 ksi, but we can temper it to other strength levels.
AISI 4140 steel is usually supplied ready heat treated to 18-22HRC. If further heat treatment is required annealed AISI 4140 should be heated slowly to 840-875C and after adequate soaking at this temperature quench in oil. Temper as soon as the tools reach room temperature.
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.
What is 4140 Steel? AISI 4140 steel also can be called DIN 1.7225 and JIS SCM440 steel. 4140 alloy steel has high fatigue strength and low notch sensitivity. Low-temperature impact toughness is also very high, no obvious temper brittleness. It is mainly used after quenching and tempering state.
AISI 4140 Steel Hardening & Quenching 4140 Steel is usually used at 18-22 HRc, If needs, AISI 4140 alloy steel can be hardened or Quenching by cold work. Quenching medium: oil
This study presents the results of a finite element (FE) simulation of the quenching of an AISI 4140 steel C-ring in oil, covering the analysis of the distortion caused by both thermal contraction and phase transformation. Furthermore, the distortion behavior during the cooling
AISI 4140 steel is usually used after quenching and tempering. During the heat treatment process in industry production, there are some problems, such as quenching cracks, related to water-cooling and low hardness due to oil quenching.
