Product Introduction

NM400 vs NM450

The hardness value range of NM400 is 370-430HB, and the hardness value range of NM450 wear-resistant plate is 420-480HB.

Hardox400 wear plate ≤0.22≤0.70≤1.60≤0.025≤0.015≤0.80≤0.50≤0.25≤0.004

Hardox450 wear plate ≤0.25≤0.70≤1.60≤0.025≤0.010≤0.50≤0.25≤0.25≤0.004

The number 400, 450, indicates the Brinell hardness of the wear plate, the higher the hardness, the higher the yield strength and tensile strength, the service life is definitely 450 the highest, 400 the worse. However, due to the high hardness, the related wear-resistant plate processability has also become worse, such as the bending radius of the wear-resistant plate, and the cost of drilling the wear-resistant plate need to be considered. Choosing the right wear-resistant steel plate is the most important thing, is to pursue longer life or moderate life but easy to process.
