NM500/XAR500/HARDOX500/AR500

NM500 wear-resistant steel is a steel plate with high strength and high wear resistance, and its excellent performance has made it widely used in many industrial fields. The following is a detailed introduction to NM500 wear-resistant steel:

1、 Hardness

The Brinell hardness value of NM500 wear-resistant steel plate reaches over 500HBW, which enables it to effectively resist wear and prolong the service life of equipment.

2、 Chemical composition

The chemical composition of NM500 wear-resistant steel is precisely controlled to ensure its excellent performance. The main elements include carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), as well as alloying elements such as chromium (Cr), molybdenum (Mo), etc. The specific content range is as follows:

Carbon (C): ≤ 0.38%, is a key element that determines the hardness and strength of steel.

Silicon (Si): ≤ 0.70%, capable of deoxidizing and improving the strength of steel.

Manganese (Mn): ≤ 1.70%, increases the hardenability and strength of steel, while improving its hardening ability.

Phosphorus (P) and sulfur (S): controlled below ≤ 0.020% and ≤ 0.010%, respectively, to avoid adverse effects on the toughness and brittleness of steel.

Chromium (Cr) and molybdenum (Mo): controlled below ≤ 1.20% and ≤ 0.65%, respectively, to enhance the wear resistance and corrosion resistance of steel.

3、 Mechanical performance

NM500 wear-resistant steel has excellent mechanical properties, including high strength, high hardness, and good toughness. Specifically manifested as:

Yield strength: above 500MPa, capable of withstanding large pressures and loads.

Tensile strength: generally between 480 and 525 MPa, exhibiting excellent tensile performance.

Elongation rate: performs well, ensuring that the steel plate can undergo certain plastic deformation under stress without being easily broken.

4、 Application Fields

Due to its high strength, high wear resistance, and excellent machinability, NM500 wear-resistant steel is widely used in various fields, including but not limited to:

Mining machinery: used for manufacturing wear-resistant plates, screen plates, chutes and other components to improve the wear resistance and service life of equipment.

Construction machinery: Used for manufacturing wear-resistant components of excavators, loaders, bulldozers, and other equipment, such as buckets, cutting plates, etc.

Engineering machinery: Wear resistant plates for equipment such as rollers and graders, enhancing the durability and stability of the equipment.

Port machinery: used for manufacturing key components such as loading and unloading equipment, conveyor belts, etc., to ensure stable operation of equipment in harsh environments.

Shipbuilding: used for ship structure, bottom protection plate and other parts to improve the safety and stability of ships.

Petrochemical industry: used to manufacture equipment such as reaction vessels, storage tanks, and pipelines to ensure normal operation under extreme conditions.

Environmental protection equipment: used for manufacturing waste treatment equipment, sewage treatment equipment, etc., to contribute to the cause of environmental protection.

5、 Processing and cutting

NM500 wear-resistant steel plate can be processed and cut in various ways to meet the needs of different shapes and sizes. The common processing methods include cold cutting and hot cutting. Cold cutting includes water jet cutting, shearing, sawing or abrasive cutting; Thermal cutting includes oxygen fuel flame cutting, plasma cutting, and laser cutting. During the cutting process, due to the high hardness and thickness of NM500 steel plate, there may be issues such as cutting cracks. To prevent the occurrence of cutting cracks, measures such as preheating cutting, low-speed cutting, slow cooling after cutting, and heating after cutting can be taken.

In summary, NM500 wear-resistant steel plays an important role in industrial production due to its high strength, high wear resistance, and wide range of applications. In the process of processing and use, it is necessary to pay attention to selecting appropriate processing methods and process parameters, and strengthen quality control and inspection work to ensure the performance and quality of the product.
