Product Description

NM400, NM500, and NM450 are all high-strength wear-resistant steel plates that are commonly used in industries such as mining, construction, and manufacturing.

NM400 NM450 NM500 steel Plate are all grades of wear-resistant steel plates, where "NM" stands for wear-resistant, and the following number indicates its average Brinell hardness.
NM400 has a hardness of 360-440 HBW, NM450 has a hardness of 420-480 HBW, and NM500 has a hardness of 470-530 HBW. This means that NM500 is the hardest and most wear-resistant of the three, followed by NM450 and then NM400.

Wear-resistant steel plates are mainly divided into two types: alloy wear-resistant steel plates and composite wear-resistant steel plates.
 

 

Alloy wear-resistant steel plates are nm400, JFE-EH400, DILLIDUR 400, etc. Composite wear-resistant steel plates are made by surfacing a layer of ordinary steel plates. , make a wear-resistant alloy layer, so it is also called bimetallic wear-resistant steel plate.

NM500 is a high-strength wear-resistant steel plate with high wear resistance and a Brinell hardness value of 500 (HBW).

It is mainly used to provide protection in occasions or parts that require wear resistance, making the equipment last longer and reducing maintenance costs.

NM500 wear-resistant steel plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery, abrasive tools, bearings and other product parts.

450 wear-resistant steel plate, 450 is a wear-resistant steel plate with a Brinell hardness of 450HB and has good cold bending properties. 450 has very good weldability

Abrasion resistant steel plate is a plate which is high in carbon and alloyed with a range of different elements such as carbon and boron.

Abrasion resistant steel plate is usually produced using a quenching process, which increases the hardness of the steel and forms a unique grain structure.

Specifically, NM400 has an average Brinell hardness of 400, NM450 has an average Brinell hardness of 450, and NM500 has an average Brinell hardness of 500.

These wear-resistant steel plates are mainly used in situations or parts that need to withstand wear and impact, such as mining machinery, metallurgical machinery, road construction machinery, engineering machinery, etc.

The difference between NM400, NM450 and NM500 wear-resistant steel plates lies in their hardness and usage occasions.

Generally speaking, the higher the hardness of the wear-resistant steel plate, the better its wear resistance, but it is also more susceptible to embrittlement.

Therefore, when selecting wear-resistant steel plates, it is necessary to select the appropriate grade and hardness according to the actual use environment and requirements.

For example, in situations where it is necessary to withstand greater impact and wear, you can choose the higher hardness NM500 wear-resistant steel plate; and in some situations where the wear is relatively light, you can choose the lower hardness NM400 wear-resistant steel plate.

In addition, it should be noted that the performance of wear-resistant steel plates not only depends on its hardness and grade, but also on its chemical composition, organizational structure, production process and other factors.

Therefore, when choosing a wear-resistant steel plate, in addition to considering its grade and hardness, you also need to understand the production process and quality control level of its manufacturer to ensure that you purchase wear-resistant steel plates with reliable quality and stable performance.

NM400 wear-resistant plate is a special steel plate with high wear resistance, and its average hardness is 400 Brinell hardness.

This kind of wear-resistant plate is mainly used in occasions or parts that need to withstand wear and impact, such as mining machinery, metallurgical machinery, engineering machinery, coal machinery, railway vehicles, concrete mixing stations, asphalt mixing stations, cement production lines and other industries.

In these areas, NM400 wear-resistant plates can significantly increase the service life and performance of equipment and reduce the frequency and cost of repairs and replacements.

NM450 steel plate is a special steel plate with excellent wear resistance and high hardness. It is suitable for various occasions that need to withstand wear and impact.

NM500 wear-resistant plate is a high-strength wear-resistant steel plate with an average Brinell hardness of 500 and excellent wear resistance, impact resistance and bending resistance.

This kind of wear-resistant plate is suitable for various occasions that require high strength, high wear resistance and high impact resistance, such as mining machinery, engineering machinery, construction machinery, shipbuilding and other fields.
