NM400 is a high-strength wear-resistant steel plate known for its excellent wear resistance and toughness. Here are some key features, applications, and common information about NM400:
Features:
Wear Resistance: NM400 exhibits exceptional resistance to abrasion, erosion, and impact, making it suitable for harsh working environments with high wear and tear.
High Strength: It possesses high strength and hardness, allowing it to withstand heavy loads and impact forces.
Weldability: NM400 offers good weldability, allowing for ease of fabrication and assembly.
Machinability: It can be machined using conventional methods, enabling the production of complex parts and components.
Applications:
Mining and Construction Machinery: NM400 is extensively used in mining equipment, earth-moving machinery, dump truck bodies, excavator buckets, and wear liners for crushers and chutes.
Material Handling: It finds applications in industries involving bulk material handling, such as conveyor systems, hoppers, and wear-resistant liners.
Cement and Steel Production: NM400 is utilized in cement plants, steel mills, and foundries for equipment subjected to abrasion and impact, including crushers, hoppers, and cyclones.
Recycling and Waste Management: It is applied in waste sorting and recycling equipment, shredders, and wear plates for waste containers and compactors.
Common Information:
Standard: NM400 complies with the Chinese standard GB/T 24186-2009 for wear-resistant steel plates.
Hardness: NM400 typically exhibits a hardness range of 360 to 440 HBW (Brinell hardness).
Thickness and Size: NM400 is available in thicknesses ranging from 3mm to 100mm, with common widths of approximately 1500mm to 3000mm and lengths of 3000mm to 12000mm.
International Equivalents: NM400 is comparable to internationally recognized wear-resistant steel grades such as Hardox 400 (Sweden) and AR400 (USA).
NM400's exceptional wear resistance, high strength, and versatility make it a preferred choice for various industries requiring durable and abrasion-resistant materials.
