NM400 WEAR RESISTANT STEEL PLATE

Product introduction

NM400 Wear Resistant Steel Plate

NM400 is high strength wear resistant steel plate. The NM400 has quite high mechanical strength; Its mechanical properties are 3 times to 5 times that of ordinary low alloy steel plates. It can significantly improve the wear resistance of mechanical related parts. Therefore, improve the service life of machinery; The surface hardness of the product usually reaches 360 ~ 450HB. Used for mining and all kinds of construction machinery wear-resistant parts processing and manufacturing applicable structural steel plate.

1. Grade: NM400
2. Type: High strength wear resistant steel plate
3. Application: Construction machinery, mining machinery, etc
4. Name source: “Nai” and “grinding” Chinese pinyin first letter, 400 is the Brinell hardness value HB value

NM400 Wear Resistant Steel Plate Definition

NM400 is a kind of wear-resistant steel plate. NM – represents wear-resistant use of “resistant” and “grinding” Chinese pinyin first letter 400 is the Brinell hardness value HB value. (The hardness value of 400 is generalized, and the hardness value range of domestic NM400 is 360-420.)
NM400 wear-resistant steel plate is widely used in construction machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other parts. Excavator, loader, bulldozer bucket board, blade board, side blade board, blade. Crusher lining plate, blade.
The delivery status of wear-resistant steel plate is: quenching and tempering (that is, quenching and tempering)
 

NM400 Chemical Component

NM400 Mechanical Properties

The measured values of steel plate tensile properties Rp0.2, Rm and A50 are provided.

The measured values (AKV) of longitudinal impact of steel plate at 0°C and -20°C are provided.

Hardness is divided into: Rockwell hardness, Brinell hardness, Vickers hardness, Richwell hardness, Shore hardness, Barinell hardness, Nooul hardness, Weinwell hardness. Vickers hardness is expressed by HV, Rockwell hardness can be divided into HRA, HRB, HRC, HRD, Brinell hardness is expressed by Hb [N(KGF /mm2)] (HBSHBW) (refer to GB/T231-1984). It is not a simple physical concept to measure the hardness of steel parts after annealing, normalizing and tempering by Brinell hardness method in production.

It is a comprehensive index of mechanical properties such as elasticity, plasticity, strength and toughness of materials. Hardness test according to the different test methods can be divided into static pressure method (such as Brinell hardness, Rockwell hardness, Vickers hardness, etc.), scratch method (such as Mohr hardness), bounce method (such as Shore hardness) and micro hardness, high temperature hardness and other methods.

NM400 Sampling Test

Hardness test: mill off 1.0-2.5mm on the surface of the steel plate, and then carry out hardness test on the surface. It is generally recommended that you mill out 2.0mm for hardness test.

NM400 Processing

1. steel plate cutting method is suitable for cold cutting and hot cutting.Cold cutting includes water jet cutting, cutting, sawing or abrasive cutting;Thermal cutting includes oxygen fuel flame cutting (hereinafter referred to as “flame cutting”), plasma cutting and laser cutting.
2. cutting method: through the relevant process test, master the general characteristics of various cutting methods of steel plate and cutting thickness range.
3. the flame cutting method of high grade wear-resistant steel and ordinary low carbon and low alloy steel cutting as simple, in the cutting wear-resistant steel plate, need to pay attention to!!With the increase of the thickness and hardness of the steel plate, the crack tendency of the cutting edge increases.In order to prevent the generation of cutting cracks in the steel plate, the following suggestions should be followed when cutting:
