1.Wear-resistant composite steel plate refers to the common high-alloy wear-resistant layer by surfacing welding method on the common steel substrate, combined with the wear resistance of the wear-resistant layer and bearing, deformation and weldability of the substrate. Hardness of the wear layer is generally between HRC52-64.
The appearance of wear-resistant composite steel, steel surfacing surfacing on one side.
2.NM wear-resistant steel plate refers to the low-alloy steel quenched during rolling hardening or low-alloy steel after heat treatment hardened steel, also known as quenched and tempered steel. Hardness is generally HB350-500.
