NM500 vs Hardox 500

NM500 and Hardox 500 are both abrasion-resistant steel plates with similar properties, but they are produced by different manufacturers. Here's a comparison between NM500 and Hardox 500:

Origin: NM500 is a Chinese standard (GB/T 24186) for wear-resistant steel, while Hardox 500 is a trademarked brand of abrasion-resistant steel produced by SSAB, a Swedish steel manufacturer.

Chemical Composition: The chemical composition of NM500 and Hardox 500 may have slight variations due to different manufacturing processes and proprietary alloying elements. However, both grades generally contain high amounts of carbon, manganese, chromium, and other alloying elements to enhance their hardness, toughness, and abrasion resistance.

Hardness: NM500 typically has a hardness range of around 470-540 HBW (Brinell hardness), while Hardox 500 typically falls within the range of 470-530 HBW. The hardness level indicates their ability to withstand abrasive wear and impact.

Availability and Recognition: Hardox 500 is a well-established and widely recognized brand in the global market. It has gained a reputation for its consistent quality and performance across diverse industries. NM500, on the other hand, may be more commonly found in China and some Asian markets.

Applications: Both NM500 and Hardox 500 find applications in industries that require high resistance to wear, such as mining, construction, quarrying, and recycling. They are suitable for use in components exposed to abrasive environments, including buckets, liners, crushers, chutes, and conveyors.

When choosing between NM500 and Hardox 500, factors like availability, regional preferences, specific project requirements, and compatibility with relevant standards and regulations should be considered. Both grades offer excellent abrasion resistance, and the final selection depends on the specific needs and preferences of the application.
