NM550 Steel Plate is an ultra-high-performance abrasion-resistant steel plate, designed for the most extreme wear conditions. With a minimum Brinell hardness of 550 HB, it delivers exceptional resistance to severe scraping, impact, and erosion, outperforming lower NM grades. Crafted from high-alloy steel, it balances extreme hardness with necessary toughness, allowing limited fabrication through specialized cutting and welding. Widely used in heavy mining machinery, dredging equipment, and high-wear industrial components, it significantly extends equipment life, minimizes maintenance, and ensures reliability under intense abrasive stress, making it ideal for critical, high-wear applications.
