Hardness of NM450 Abrasion resistant steel plate/Sheet
NM450 has a Brinell hardness (HB) rating of approximately 450, which indicates its excellent resistance to abrasion and wear.
Application of NM450 Abrasion resistant steel plate/Sheet
NM450 abrasion resistant steel plate/sheet is commonly used in industries such as mining, construction, agriculture, and manufacturing where materials are subjected to heavy wear and abrasion. It is suitable for applications such as buckets, bulldozers, crushers, conveyor systems, chutes, and various types of equipment exposed to abrasive environments.
Fabrication and Welding of NM450 Abrasion resistant steel plate/Sheet
NM450 can be cut, formed, and welded using conventional methods. However, it is important to follow proper procedures to maintain the material's properties during fabrication.
NM450 offers excellent resistance to abrasion, impact, and sliding wear, making it a preferred choice for applications where durability and wear resistance are critical. Its high hardness and strength enable it to withstand harsh working conditions, increasing the service life of components and reducing maintenance costs.
Note that specific requirements and specifications for NM450 may vary depending on manufacturers and suppliers. It is advisable to refer to the relevant standards and product documentation for detailed information on the material's properties and recommended processing guidelines.
