Vol.10, No.3 Effect of Heat Treatment on Mechanical Properties 301 2. MATERIALS AND METHOD Sample of NST 37-2 steel bar with 25 mm diameter and 10 m long was purchased from a local market located in Ibadan, south-western, Nigeria. The chemical composition of the steel sample
Apr 24, 2017· It is used to make power shovels, steel balls, nozzles, surgical instruments, crushers and plates for rock-processing. Steel with a sufficient amount of chromium that undergoes heat treatment hardens to form chromium carbide particles, which increase the wear resistance of the steel alloy.

Here are 7 ways that steel can fail as a result of Quench Cracking from heat treatment. Overheating during the austenitizing portion of the heat treatment cycle can coarsen normally fine grained steels. coarse grained steels increase hardening depth and are more prone to quench cracking than fine grain steels. Avoid over heating and overly long dwell times while austenitizing.
Effects of Heat Treatments on Steels for Bearing Applications K. Clemons, C. Lorraine, G. Salgado, A. Taylor, J. Ogren, P. Umin, and O.S. Es-Said (Submitted July 31, 2006; in revised form August 29, 2006) AISI 52 100, 440C, REX20, and Crucible CRU80 steel samples were exposed to 16 different heat treatments to vary the levels of retained austenite.
NTN TECHNICAL REVIEW No.71（2004） Fig. 2 illustrates a schematic of the test rig, and Table 1 shows the test conditions. Table 2 shows the results of a point contact type rolling contact fatigue test. Regarding the steel specimen possessing normal cleanliness, the L 10 life of the carbonitrided material was found to be 3.1 times
Jun 09, 2001· As a rule of thumb, within the tempering range for a particular steel, the higher the tempering temperature the lower the final hardness but the greater the toughness. It should be noted that not all steels will respond to all heat treatment processes, Table 1 summaries the response, or otherwise, to the different processes.
potential competitive advantages. This paper presents an exploratory study of the effects of heat treatment on materials used in automobiles, major ones being steel and aluminium. This paper addresses the benefits of heat treatment on metals like aluminium on a comparative basis and stresses upon the application of same in

A variety of heat treatment techniques exist for case hardening gears. Heat treatment processes can be tailored to maximize the life and optimize the performance of a gear in its service application by tailoring the heat treatment to produce specific desired properties.
Workhardening Behaviour and Microstructural Analysis of Failed Austenitic Manganese Steel Crusher Jaws large amount of carbon gives these steels their high impact toughness and high strain hardening rate capacity, which gives them their excellent impact abrasion resistance. Hence, solution treatment makes these steels very soft (190 HB)
Heat treating (or heat treatment) is a group of industrial and metalworking processes used to alter the physical, and sometimes chemical, properties of a material. The most common application is metallurgical. Heat treatments are also used in the manufacture of many other materials, such as glass. Heat treatment involves the use of heating or ...
