High Strength Wear Resistant Steel Plates NM600

High Strength Wear Resistant Steel Plates NM600

NM600 is read as wear-resistant 600, "NM" refers to the wear-resistant plate, the first letter of the word "resistant" and "grinding", 600 is the Brinell hardness value HB value. The grade is higher than NM500, NM450, NM400, NM360.

Delivery condition: tempering (quenching + tempering)

The chemical composition of the wear-resistant layer of NM600 alloy has a carbon content of 4~5% and a chromium content of 25~30%, and the volume fraction of Cr7C3 carbide in the metallographic structure reaches more than 50%, the macro hardness is HRC56~62, and the hardness of chromium carbide is HV1400~1800. Because the carbide is vertically distributed in the wear direction, the wear resistance is more than doubled compared with the cast alloy with the same composition and hardness.
