Rendón and Olsson studied the abrasive wear resistance of the steels and pointed that a combination of excessive hardness and toughness is of significance in order to obtain a excessive wear resistance. Luo et al. reported the amount of retained austenite decreased and the martensite/austenite islands decomposed with the rise of tempering temperature. They also found the distribution of carbides alongside prior austenite grains introduced concerning the temper embrittlement. Abdollah-Zadeh et al. reported that rising the tempering temperature decreases the yield and ultimate tensile strengths, but increases the ductility.
The microstructure of the steel primarily consisted of tempered martensite and ferrite. Tempered troosite was obtained when the tempering temperature was over 280 °C. The hardness decreased continuously with the rise of tempering temperature. The same hardness was obtained when tempered at 260 °C and 300 °C, because of the interaction of Fe3C carbides and dislocations. The impression toughness elevated first and reached a peak worth when tempered at 260 °C.

The subsurface of the steel with the best wear resistance was shown in Figure 8b. Some particles could be wrapped within the deformed matrix, and other particles continued to cut the matrix as the wear and tear time was prolonged. Figure 8e exhibits the typical minimize habits of the embedded particles. The lost matrix is shown in Figure 8e, circled utilizing a white line.
GB/T 24186 NM500 is high-strength wear-resistant steel, which has a high resistance to abrasion, Brinell hardness value reaches 500 (HBW) is to provide the required protection to wear the occasion or parts of the device for longer life, reduced maintenance brought maintenance and downtime, and the corresponding reduction in capital investment.
Name: N is “wearable” in the “resistance” of the first phonetic alphabet.
M is “wearable” in the “grinding” the first phonetic alphabet.
500 Brinell hardness HB value. (500 hardness is a broad, domestic NM500 hardness value is around 500.)
Fu et al. also investigated the impact of heat treatment on the hardenability, mechanical performances, and wear resistance of a excessive carbon low alloy steel. However, there are few published studies associated to the systematical research on a 500 HB grade high power low alloy wear-resistant steel. In this work, the impact of tempering temperature on microstructure, wear behavior, and the connection between mechanical properties and wear resistance of a 500 HB grade wear-resistant steel have been researched systematically. Heat therapy is a major process for steels to obtain the optimum microstructure part which has a significant affect on the mechanical properties of the steels, particularly on the hardness and influence toughness . A mixture of adequate hardness and excessive impression toughness can present considerable abrasive wear resistance, and in addition improve the capability of absorbing impact vitality by the microstructure .

As the tempering temperature was over 260 °C, carbide precipitation would happen along the grain boundaries, which led to temper embrittlement. The finest wear resistance was obtained when tempered at 200 °C. At the initiation of the wear test, surface hardness was thought-about to be the dominant influencing issue on wear resistance. The impact Nm500 steel plate supplier of surface hardness improvement on wear resistance was far higher than the impression toughness. With the wear time extending, the crushed quartz sand particles and the cut-down burs could be new abrasive particles which would trigger additional wear.
