What is the toughness of NM500 plate?

Toughness indicates the ability of NM500 wear-resistant plate to absorb energy during plastic deformation and fracture. Toughness is divided into fracture toughness and impact toughness.

Fracture toughness is a measure of a material's ability to prevent macroscopic crack instability and growth, and it is also a toughness parameter for a material to resist brittle failure. It is an inherent characteristic of the material and is only related to the material itself, heat treatment and processing technology. It has nothing to do with the size, shape and applied stress of the crack itself.

NM500 wear plate 0 impact toughness indicates the ability of metal materials to resist damage under impact load.
