high GB/T 24186 NM500 Wear resistant steel
We produce and export GB/T 24186 NM500 Abrasion resistant steel plate,GB/T 24186 NM500 Wear resistant steel plate, GB/T 24186 NM 500 Cutting steel plate, NM 500 machined parts in 3-5days.
Hot rolled wear steel plate is excessive strength and wear resistant steel with favourable hardness and influence toughness. Abrasion Resistant Steel Plate ApplicationsThe AR235 plates are intended for moderate wear functions the place it presents improved wear resistance relative to structural carbon steel. The AR400 are premium abrasion resistant steel plates that are heat treated and exhibit by way of hardening. AR500 Wear-resistant steel plate,AR500 steel is an abrasion resistant steel plate used for high wear applications like mining or material handling.
As may be seen in Figure 4c,d, the as-quenched steel with the best hardness and the lowest influence toughness possesses the worst wear resistance. The best wear resistance is obtained when steel is tempered at 200 °C. Many reports have pointed out sufficient toughness can improve the wear resistance considerably . The steel tempered at 200 °C possesses one of the best wear resistance whose influence toughness will increase distinctly up to 38 J/cm2.
The purpose for this might be the same wear take a look at conditions and the same chemical composition. As presented in Figure 7a,b, the scratches of random orientation have been lengthy, and the dispersedly distributed adhesive pits could be seen clearly and are encircled by white strains. The embedded quartz sand particles and a few small delamination were also observed.
Standard stock in abrasion resistant steel consists of AR400 and AR500.Abrasion resistant material is used in wear purposes requiring resistance to elevated influence and sliding. This standard applies to mining, development, agriculture and development equipment wear-resistant structural parts with thickness less than eighty mm of steel.

GB/T 24186 NM500 Wear resistant steel chart
- Studies of various hardness classes lower than 500 HB have been extensively printed .
- Also, the results of quenching strategies on microstructure and mechanical properties have been printed .
- Fu et al. also investigated the impact of warmth treatment on the hardenability, mechanical performances, and wear resistance of a excessive carbon low alloy steel.
- However, there are few printed research related to the systematical analysis on a 500 HB grade high power low alloy wear-resistant steel.
- In this work, the impact of tempering temperature on microstructure, wear habits, and the relationship between mechanical properties and wear resistance of a 500 HB grade wear-resistant steel were researched systematically.
Rendón and Olsson studied the abrasive wear resistance of the steels and pointed that a combination of excessive hardness and toughness is of importance in order to acquire a high wear resistance. Luo et al. reported the quantity of retained austenite decreased and the martensite/austenite islands decomposed with the increase of tempering temperature. They additionally found the distribution of carbides alongside prior austenite grains introduced about the temper embrittlement. Abdollah-Zadeh et al. reported that rising the tempering temperature decreases the yield and supreme tensile strengths, but will increase the ductility. However, the tensile energy decreases at the next price in contrast with that of yield power, indicating a decrease price of labor hardening with elevated tempering temperature.
As a end result, intergranular fracture happens, and the impression toughness deteriorates . Thus, the brittle temperature vary is between 280 °C and 300 °C, which must be prevented when tempering. NISCO can produce low alloy excessive strength abrasion resistant steels of grade NM360, NM400, NM450, NM500 and NM550 which have high strength and good abrasion resistant properties, good toughness and weldability, glorious processing properties and formability. Bebon International is knowledgeable GBT24186 NM400 excessive energy abrasion resistant steel plates for development machine steel exporter and a steel Stockist in china.
With the rolling of the lower specimen, the embedded particles would move and the microcracks would lengthen. Similar behavior may also be noticed in Figure 8f. Figure 7 shows the wear surfaces of the quenched steel and steels tempered at totally different temperatures. Similar wear surfaces consisting of scratches, embedded quartz sand particles, microcracks, delamination, and adhesive pits had been obtained. However, small variations can be nonetheless noticed between the wear-resistant steels.

As shown in Figure 8, similar subsurface layers have been obtained with embedded quartz sand particles and microcracks distributed on them. However, some differences could still be discovered by way of the images. As shown in Figure 8a, weak hardenability was obtained due to the excessive hardness of the steel. The distinction of the hardness between the deformation layers and matrix was small.
