NM450 steel plate is a high-strength wear-resistant steel known for its toughness and abrasion resistance properties.
It belongs to the NM series of abrasion-resistant steels, typically used in demanding applications where resistance to wear and impact is crucial.
Properties:
Hardness: Typically achieves a hardness of around 420-480 HBW (Brinell Hardness).
Strength: Offers high strength and toughness, suitable for withstanding impact and abrasion.
Wear Resistance: Shows excellent resistance to abrasive wear, extending the lifespan of components.
Machinability: Can be machined through appropriate methods due to its hardness.
Applications:
Mining Equipment: Used in mining machinery, earthmoving equipment, and dump truck bodies to withstand abrasive materials.
Construction Machinery: Employed in construction equipment like excavator buckets, bulldozer blades, and concrete mixer drums.
Quarrying Industry: Suitable for applications involving crushing and screening equipment subjected to wear.
Material Handling: Utilized in conveyor systems, chutes, hoppers, and other high-wear areas.
Manufacturing Standards:
NM450 steel plates are typically manufactured according to Chinese GB/T 24186 standard or similar international standards specifying wear-resistant steel requirements.
Processing:
Cutting: Can be cut and shaped using plasma cutting, laser cutting, or other appropriate methods.
Welding: Requires proper techniques to maintain the material's wear-resistant properties after welding.
Maintenance:
Regular inspection and maintenance are crucial to ensure continued performance under abrasive conditions.
Proper handling and storage practices help preserve the integrity of NM450 steel plates.
Considerations:
Selection based on specific application requirements such as wear resistance, toughness, and hardness.
Adherence to recommended welding procedures and post-treatment processes to retain material properties.
NM450 wear-resistant steel plates are essential components in industries where equipment is exposed to abrasive environments, providing reliable protection against wear and extending the lifespan of machinery and structural components subjected to harsh operating conditions. Selecting NM450 steel plates for appropriate applications ensures enhanced durability and performance in high-wear environments.
