Qual è la differenza tra NM500 e AR500?

Wear resistant steel plates play a vital role in many industries, especially in those environments that require high-intensity friction and impact. NM500 and AR500 are two widely used wear-resistant steel plates, each with its own characteristics in terms of hardness, wear resistance, impact resistance, etc. So what is the difference between them? This article will explore the difference between NM500 and AR500 from multiple angles, and I hope it will be helpful to everyone.

What Is NM500?

NM500 is a steel plate with high-intensity wear resistance as its main feature, usually with a hardness of 500HB, and can withstand extremely high friction and wear. It meets certain international standards, such as China's GB/T24186-2009, etc., and there are also relevant certifications and standards internationally, such as ISO, ASTM, etc.

What Is AR500?

AR500 is a wear-resistant steel plate with high hardness and impact resistance. The "AR" in its name stands for Abrasion Resistant, and the "500" indicates the Brinell Hardness of the steel plate, which is about 500 HB (Brinell Hardness 500). It has extremely strong impact resistance and wear resistance. It is often used in protective armor, military facilities, and other high-impact applications.

What Is the Difference Between NM500 and AR500?

Durezza:

NM500: NM500 steel plate has a hardness of 500HB. Although it has a high hardness, it performs well in the face of lower-intensity impact and wear. Its hardness is suitable for high-friction environments, especially in long-term work in mining, steel and other fields, which can effectively reduce component wear.

AR500: It also has a hardness of 500HB, but because it focuses more on impact resistance during the manufacturing process, it can maintain better toughness under high-intensity impact. Compared with NM500, AR500 can better withstand high-speed and strong impact loads.

Resistenza all'usura:

NM500: NM500 has excellent wear resistance and is suitable for medium-intensity friction and wear environments, such as mining machinery, construction equipment, etc. Its high hardness can effectively resist conventional friction and wear.

AR500: AR500's wear resistance is very outstanding among high-hardness steel plates, and is particularly suitable for high-impact and high-friction environments. AR500 has a high hardness and can withstand extreme wear, such as high-speed wear, sand and stone impact, etc. Its wear resistance is usually higher than NM500, and it is suitable for application scenarios requiring extremely high wear resistance, such as military protection, mining equipment, etc.

Resistenza all'impatto:

NM500: Mainly characterized by wear resistance, it is suitable for heavy-load mechanical working environments and can withstand continuous friction and wear.

AR500: Although it also has strong wear resistance, it performs better in high-impact and high-speed impact environments, and is suitable for protection, armor and other fields.

Adattabilità ambientale:

Both can adapt to harsh working environments, but AR500 performs more stably in extreme temperatures and high impact environments. NM500 has better durability under long-term friction and load conditions.

Processing and Molding Performance:

NM500 has relatively good processing performance and is suitable for processing into wear-resistant parts with complex shapes and specifications. AR500 has a higher hardness, and special attention should be paid to the selection of tools and processing technology during processing.

NM500 and AR500, How To Choose?

Requisiti delle applicazioni:

Generally, if the application scenario requires long-term friction and wear and lighter impact, it is recommended to choose NM500. If the application scenario involves high-intensity impact or even bulletproof requirements, AR500 is a more suitable choice.

Limiti di spesa:

If the budget is limited, but high wear resistance is required, NM500 is a cost-effective choice. If the budget is sufficient and strong impact resistance and wear resistance are required, AR500 may be more in line with the needs.

Fornitori:

Different suppliers may have differences in product quality, production scale and price. It is crucial to choose a reliable supplier.

Although NM500 and AR500 have similar hardness, they have significant differences in performance. NM500 focuses more on wear resistance and is suitable for heavy-load wear environments, while AR500 is good at impact resistance and is widely used in protection, military and high-impact working environments. Choosing the right material requires comprehensive consideration of multiple factors such as specific application scenarios, budget, and suppliers.
