NM550 Extra High Strength Wear Resistant Steel Plate - Toughness and Wear Resistance, Responding to the Limit (Conforms to GB/T 24186 Standard)
Product Overview
NM550 is an extra-high strength grade wear-resistant steel in GB/T 24186-2009 standard, which represents the advanced level of domestic wear-resistant steel. It further enhances the hardness and strength on the basis of NM500, and is designed for extreme working conditions subject to the harshest abrasion and moderate impact.
Core properties and advantages
Extreme wear resistance: Hardness of HBW 520-580 for the most demanding abrasive wear environments.
Extremely high load carrying capacity: Very high yield strength for thin-walled, lightweight and heavy equipment components.
Excellent toughness reserve: Despite the extreme hardness, the necessary impact toughness is maintained by technical means.
Lightweight design possibilities: Thinner NM550 can meet or exceed the performance of thicker grades of lower grades of steel, enabling equipment weight reduction.
Typical application areas
Large mining dump truck carriages.
Power crusher hammers and liners.
Neutral mill rolls and disc linings in the cement industry.
Edge plate of large hopper and pile reclaimer in iron and steel mills.
