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 Alloy Metric Round TG&P Bar - 4140 Turned Ground 4140 HT Turned, Ground & Polished Precision Shafting material is quench & tempered, stress relieved, machine straightened and turned ground & polished.I.T.S. stocks this grade in both metric and standard sizes. Alloy 4140 is widely used as an alternative to carbon steel
Superior Steel Alternative to. 4140 Alloy Steel. Pennsylvania Steel Corporation presents an alternative to SAE 4140 alloy steel. FLEXOR®'s chemistry and mechanical properties are comparable, if not superior to 4140 alloy steel and thusly, can be utilized in most of the same applications. 4140 Heat Treated Steel Plate Precision Grinding, Inc.4140 HR Steel Plate; 4140 Flat Bar; Oil Quenched & Tempered . Standard Hardness. 4140 PH has a standard, industry recognized Rockwell C Hardness rating of 28 32. Most sources recognize and tend to prefer quoting and requesting the Rockwell C Scale. 4140PH ranges from Brinell Hardness 270 300. Thick 4140 AN (in the annealed condition) is flame cut, then annealed onsite in our furnace. 4140HW Alloy Steel Technical DataTimkenSteels 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,
4150 Hot Rolled Quenched & Tempered About 4150 HR Quenched and Tempered (Q&T) This is a Resulphurized, Hot Rolled, Quenched and Tempered, Stress Relieved steel. 4150R HR Q&T SR is a free-machining alloy steel that provides an outstanding combination of heat treated properties and superior machinability. AISI 4140 QT/SR TGP Alloy Round Bar Manufacturer AISI 4140 Chrome- 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 QT/SR TGP Alloy Round Bar Manufacturer Preheat the steel carefully, then raise the temperature to 1150-1200°C for forging. Do not forge below 850°C. 2)Annealing. Heat the AISI 4140 slowly to 800-850°C and allow enough time for the steel to be thoroughly heated. Cool slowly in the furnace to 480°C followed by air cooling. 3)Stress Relieving
Round Bars :Spec. Diameter, in. Diameter Tol. Alloy Steel:Round Bar:4130-Norm., 4140-Ann., 4340-Norm. Cold Finish:Up to 1.5, incl. +/- 0.004" Alloy Steel Are 4140 HT and 4140 HTSR the same thing?Nov 23, 2011 · Heat treated 4140 is oil quenched, so it definitely gets cold somewhere in there. It would most likely be Rc45 to Rc50 if simply heat treated. The stress relief is, to my way of understanding it, way overdrawing the temper of the hardened (quenched) bar, and the hardness is much reduced from maximum so as to reduce the quench stress.
