GB/T24186 NM400 high strength wear resistant steel plates for construction machine steel plate
GB/T 24186 NM400 high strength wear resistant steel plate has quite high mechanical strength. The mechanical properties of NM400 steel is 3 times to 5 times than that of ordinary low Alloy steel plates. Therefore, material NM400 can significantly improve the wear resistance of related machine components, which further improve the service life of machinery and reducing the production cost. The surface hardness of GBT24186 NM400 wear resistant steel plate is usually 360 to 450HB.
GB/T24186 NM400 wear resistant steel plate chemical composition:
Grade | C | Si | Mn | P | S | Cr | Ni | Mo | Ti | B | Als |
NM400 | ≤0.30 | ≤0.70 | ≤1.60 | ≤0.025 | ≤0.010 | ≤1.00 | ≤0.70 | ≤0.50 | ≤0.050 | 0.0005-0.006 | ≥0.010 |
GB/T24186 NM400 wear resistant steel plate mechanical properties:
Grade | Thickness | Tensile Strength | Elongation | Impact energy | HBW |
mm | Rm/MPa | % | J/-20℃ | ||
NM400 | ≤80 | ≥1200 | ≥10 | ≥24 | 370-430 |
GBT24186 NM400 high strength wear resistant steel plates are widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other products. For example: excavator, loader, bulldozer bucket board, blade plate, side blade plate, blade, lining plate and blade of the crusher, etc.
