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.
At the initiation of the wear and tear test, floor hardness was considered to be the dominant influencing issue on wear resistance. The effect of floor hardness improvement on wear resistance was far higher than the influence toughness. With the wear time extending, the crushed quartz sand particles and the cut-down burs would be new abrasive particles which would cause further wear.
You can even choose from ship plate, container plate, and boiler plate nm500 wear resistant steel plate, as well as from sgs nm500 wear resistant steel plate, and whether nm500 wear resistant steel plate is sizzling rolled, or chilly rolled. ballistic wear resistant steel plate nm500 nm400 Alloy & Abrasion Resistant Steel Plate .
GB/T 24186 NM500 Wear-resistant ar400 carbon steel
The surface hardness is the dominant influencing factor in this take a look at condition. The wear behavior was further studied based on the wear and tear subsurface layers of the quenched steel and steels tempered at completely different temperatures.
For chemical composition consultation and free pattern, welcome to contact our manufacturing facility. NM400 is one type of Chinese wear/abrasion resistant steel plates, which is nicely obtained in middle east and Africa. An NM400 wear-resistant steel was scorching rolled and then the plates had been heat-handled by direct quenching and tempering and reheat quenching and tempering techniques, respectively.

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.)
GB/T 24186 NM500 Wear resistant steel sheet
The steel tempered at 200 °C possesses one of the best wear resistance whose influence toughness increases distinctly up to 38 J/cm2. However, the rising influence toughness does not make a relentless improve in wear resistance. Hardness can cut back the penetration of particles and enhance the wear and tear resistance, thus, the steels with nearly similar hardness should have the acquainted wear performance .
As shown in Figure 3b, the carbide precipitations can hinder the movement of dislocation and make yield strength increase consequently. Otherwise, the impact toughness will increase considerably because of the relieving of internal stress and exercise of carbides . When the tempering temperature is over 260 °C, the diffusion velocity of carbon will increase Nm500 steel plate supplier, which can speed up the decomposition of martensite and the separation of carbides . A further lower of carbon content material in martensite makes the tensile power and yield energy decrease continually.
As proven in Figure 4d and Figure 6b, the mechanical properties of the steel tempered at 260 °C are higher than the steel tempered at 300 °C. With the tempering temperature increasing from 260 °C to 300 °C, more carbides separate out and they’d assist power the matrix. While the strengthening conduct of carbides cannot offset the softened action of matrix . As a result, the hardness of the steel decreases slightly. As discussed above, enough surface hardness performs a dominant function in enhancing the wear and tear resistance.
GB/T 24186 NM500 Abrasion resistant steel ar400
A combination of enough hardness and high impact toughness can provide appreciable abrasive wear resistance, and also improve the capability of absorbing influence vitality by the microstructure . There have been few research on the impact of tempering behavior on abrasive wear resistance of a selected grade steel. Cao et al. studied the tempering conduct of lath martensitic wear-resistant steels with a hardness lower than 450 HB. They found the addition of Mo and Ni had no vital effects on the carbides morphologies when the tempering temperature was below 350 °C.
