With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
42CrMo4 is a medium carbon Cr-Mo alloyed steel that is frequently used in a quenched and tempered condition when a good combination of strength and toughness is required. It also has high fatigue strength and wear resistance, making it an excellent candidate for manufacturing vessels working under high-pressure hydrogen gas .

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.
4140 Tempering Curve 4140 Tempering Curve paras99 (Automotive) (OP) 11 Sep 12 10:18. Hi, does anyone know if there is data available for a hardness vs temperature curve for 4140 steel at a certain time. I have been looking everywhere and cant seem to find it. Your help would be much appreciated.
ASTM 52100 Bearing Steel | 1.3505 | 100Cr6 | SUJ2 | EN31. ASTM A295 is specification which covers 52100 high carbon bearing quality steel to be used in the manufacture of anti-friction bearings. And 52100 bearing steel is the most common steel grade in ASTM A295 standard for high-carbon anti-friction bearing steel.
Mechanical properties of 4140 steel. 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.
Results indicated that same mechanical properties for 41Cr4 and 42CrMo4 can be achieved by tempering 41Cr4 about 50 C lower temperature than for 42CrMo4.

Advances in Materials Science and Engineering is a peer-reviewed, Open Access journal that publishes original research articles as well as review articles in all areas of materials science and engineering.
Heat to 150 o C - 200 o C as required, hold until temperature is uniform throughout the section, soak for 1 - 2 hours per 25 mm of section, and cool in still air.N.B. Tempering will improve the toughness of both case and core, with only a slight reduction in core strength and case hardness.
End Quench curves and the resulting grain size curves proposed introduce a better defined heating and cooling cycle. The improved model obtained will optimistically result in less time spent in research and development.

Fatigue Performance As Measured By Fatigue Strength Quenched and Tempered Steels Posted on November 12, 2013 by Steel Market Development Institute In a recent posting, a comparison of the fatigue properties for normalized steels (163-259 BHN) showed that the strain-life curves fell within a rather narrow band, especially in the long-life regime.
3) Tempering recommendations from the ASM heat treaters guide for 4140-4142 is a minimum of 400F. This leaves near full hardness. The following table is extrapolated from a hardness graph given in Brinell Hardness with nearest points taken from a conversion table for Rockwell hardness. Tensile values are generic, not specifically for 4140.
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.
