General characteristics of 4140 Alloy Steel. AISI or SAE 4130 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents. Its chemical composition is as follows AISI/SAE 4140 grade is a versatile alloy with good atmospheric corrosion resistance and reasonable strength.
affected if it is welded in the heat treated condition, and post weld heat treatment should be performed. Heat Treatment AISI 4140 alloy steel is heated at 845C (1550F) followed by quenching in oil.
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,
AISI 4140 Steel, oil quenched, 540C (1000F) temper, 25 mm (1 in.) round Categories: Metal; Ferrous Metal; Alloy Steel; AISI 4000 Series Steel; Low Alloy Steel; Carbon Steel; Medium Carbon Steel. Material Notes: As quenched hardness after oil quenching: Surface - 55 HRC, 1/2 radius - 55 HRC; Center - 50 HRC
Heat to 840 o C - 875 o C, hold until temperature is uniform throughout the section, soak for 10 - 15 minutes per 25 mm section, and quench in oil, water, or polymer as required.*Temper immediately while still hand warm. Nitriding: 4140 hardened and tempered bar can also be successfully nitrided, giving a surface hardness of up to Rc 60.
Typical Properties. AISI 4140 and 4150 is a medium carbon, chromium-molybdenum alloy steel. This steel is offered in a wide range of conditions including but not limited to: cold drawn annealed, hot roll heat treated, heat treated turned ground and polished. Typical tensile strength ranges from 114,000 PSI (Annealed Condition) up to 156,000 PSI, heat quenching 4140 alloy steel properties

1. Like with most alloys and tool steel there is a pre-heat stage to condition the metal for hardening. The metal is brought up to 1200 F slowly and held there for 10-15 minutes. 2. Then for 4140 the temperature is brought up to 1575 F, which is the austenizing temperature of 4140.
7. Heat Treatment of SAE 4140 Alloy Steel. ASTM 4140 Steel Annealing; Slowly heat to 8008500 C, keep enough time, ensure heat thoroughly. then cooling in furnace to 480 C, then cool in air. After annealing, the hardness 92 HBS Max. 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.
There are 254 4140 alloy steel properties suppliers, mainly located in Asia. The top supplying country is China (Mainland), which supply 100% of 4140 alloy steel properties respectively. 140 alloy steel properties products are most popular in South America, North America, and Western Europe.
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). A full bar means this is the highest value in the relevant set.
Alloy AISI/SAE 4140/ 4142 (UNS G 41400/G 41442) Mechanical Properties Heat treated to HRC 22 maximum for sour gas service. Minimum tempering temp 1150 F. Conforms to NACE Standard MR01-75.
Stormcrow: one of the reasons for using a higher alloy (4340, S-7, etc) than 4140 is quench reliability. While large 4140 rounds can be water-quenched, squares are a different story. Each corner of a die is a three-sided pyramid and in quenching the corners will cool very quickly, often causing "finger-nail" cracking of the corners.
AISI 4140. The greatest increase in hardness in relation to the increasing heating temperature was obtained for AISI 4140 steel. The main objective of this study was to investigate some morphological and mechanical properties of AISI 4140 steel with different normalization temperature for air, oil and water quenching environment. 2.
Polymer quenching is particularly useful for quenching high integrity alloy steel forgings that require impact testing. Heavy section AISI 4140 forgings that need good depth of hardness can be a challenge when oil quenched. Our polymer quenching hardening heat treatment can be the solution for jobs that do not respond properly to oil quenching.

The 4340 steel has good shock and impact resistance as well as wear and abrasion resistance in the hardened condition. AISI 4340 steel properties offer good ductility in the annealed condition, allowing it to be bent or formed. Fusion and resistance welding is also possible with our 4340 alloy steel.
4140 Steel is a verstatile alloy used in the tooling and other high-strength applications. 4140 is composed of chromium, molybdenum, and manganese. This low alloy steel is ideal where its high fatigue strength, torsional strength, abrasion resistance and toughness make it ideal for a number of applications.
I usually send my heat treating out, but in the little bit I have done with a few types of steel, I think W1 drill rod is the easiest. Heat 'er up as fast as you can, and stick it in the cold water quench. However, I don't think that heat technique works quite as well for 4140, because it is slower to make the phase changes.
O1 is a general-purpose tool steel that is typically used in applications where alloy steels cannot provide sufficient hardness, strength, and wear resistance. APPLICATIONS: Where greater dimensional stability in heat treatment or improved wear resistance is required, tool steels with higher alloy contents, such as A2 or D2 should be considered.
It is a bit unsatisfactory to call an alloy "4140 heat treat" since - quench and tempered - annealed - quenched but not tempered are all "heat treatments". So a name like "4140 heat treat" leaves me a bit doubtful about what I am getting for my money. So my questions are, a. What is the proper designation for the machinable version of heat , heat quenching 4140 alloy steel properties
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.
