NM 450 Wear Plate
NM450 wear plate is a high-strength, wear-resistant steel plate with a Brinell hardness of 450 HBW, known for its durability and resistance to abrasion. It's widely used in applications like mining, construction, and machinery manufacturing to extend the service life of equipment.
Key Characteristics:
High Hardness:
NM450 steel has a Brinell hardness of 450 HBW, providing excellent wear resistance.
High Strength:
It offers superior mechanical properties compared to ordinary low-alloy steel plates, with a yield strength above 950 MPa and tensile strength around 1180 MPa.
Good Weldability:
NM450 plates can be welded using standard techniques, making it suitable for various fabrication needs.
Good Cold Bending Performance:
It can be cold-bent and processed, making it adaptable to different shapes and designs.
Cost-Effective:
While it may cost more than standard steel, its durability and extended service life often make it a cost-effective choice in the long run.
Common Applications:
Mining: Buckets, liners, and other wear parts in mining equipment.
Construction: Wear plates in excavators, loaders, and bulldozers.
Metallurgy: Liners for crushers, hoppers, and other machinery.
Machinery Manufacturing: Wear plates in various types of machinery.
Conveyor Systems: Wear-resistant components in conveyor belts.
Other Applications: Skip loaders, dump trucks, and other equipment exposed to abrasion.
Comparison with Hardox 450:
NM450 is a Chinese wear-resistant steel grade, while Hardox 450 is a brand produced by SSAB.
Both grades have similar chemical compositions and mechanical properties, but NM450 is often considered more cost-effective.
What is 450 grade wear plate?
AR450 Wear Plate is one such grade that reduces the industrial wear in applications that may be caused due to rubbing, scraping, or erosion. The reduction of wear by AR450 Steel Plate leads to an increase in production time and reduction in downtime and maintenance cost.AISI AR450 Steel,JFE-EH450.
Is NM450 steel good?
NM450 steel is a high-strength, wear-resistant steel plate with an average Brinell hardness of 450 HBW. Its mechanical properties are 3 to 5 times those of ordinary low-alloy steel plates, with a yield strength above 950 MPa and tensile strength around 1180 MPa.
NM450 steel's excellent wear resistance and high hardness (430-470 HB) make it ideal for use in mining, metallurgy, construction, and machinery manufacturing. It is commonly used for wear plates, liners, and conveyor belts, significantly extending the service life of equipment.
The steel also has good cold bending and processing performance, making it versatile for various applications. Despite its high cost, its durability and economic benefits make NM450 a preferred choice in many industrial field.
What material is HBN 450 made of?
The HBN 450 and HBN 480 are chrome-molyb- denum castings, which is produced after a complex quenching and tempering process, it has a consistent hardness of up to 650 HB.
What is the difference between NM450 and Hardox 450?
NM450 is a Chinese wear-resistant steel grade, while Hardox 450 is produced by the Swedish company SSAB. Both steel grades have almost identical chemical compositions and mechanical properties, but they adhere to different standards. NM450 is considered more cost-effective compared to Hardox 450.
What is the hardness of NM450?
The Brinell hardness (HB) value of NM450 ranges from 420 to 480.
What is NM400 steel?
NM400 is a high-strength wear-resistant steel plate with mechanical properties 3 to 5 times those of ordinary low-alloy steel. It features a surface hardness of 360 to 450 HB and is widely used in engineering, mining, coal mining, environmental, and metallurgical machinery. With a high carbon content (4-5%) and chromium content (25-30%), its Cr7C3 carbides volume fraction exceeds 50%, resulting in a macro hardness of HRC 56 to 62
NM 450 is a wear-resistant steel plate with a Brinell hardness of 450 HB, which has good cold bending properties and is mainly used in wear-resistant applications. NM 450 has very good weldability. Due to the combination of high hardness, high strength, and high toughness, NM wear plates are clearly ideal for those applications with severe wear. The high wear resistance of the plate extends the service life of dump truck bodies, excavator buckets, crushers and similar equipment.
