Nm360 Nm400 Nm450 Nm400 Nm500 Xar400 Xar500 Abrasion Wear Resistant Steel Plate

Wear-resistant steel surface hardness description and identification method
High strength wear-resistant steel plate for construction machinery means that it is mostly used in large mechanical equipment in engineering
The main characteristics of "strength" is higher than the general steel plate and "high wear resistance", the selection of wear-resistant steel is important
Its wear resistance is more, and the surface hardness of the steel plate is high, which increases the wear resistance service life and wear resistance
The welding performance of the steel plate is also better, so the use of wear-resistant steel plate has been greatly increased.

Surface hardness range of steel plate:
material        Surface hardness (HB)
NM360        370-410.
NM400        410-440.
NM450        460-490.
NM500        510-560.
