How to identify the quality of wear-resistant steel plates

Appearance Quality 1. Flatness: The four corners of the flat plate are on the ground, 2. Welding cracks: evenly spaced, small cracks, not wide; 3. hardfacing layer: no obvious unevenness 4. Welding defects: within a reasonable range; 5. Surface spray paint: the paint layer is evenly thin and thick, putty, etc.; 6. Edge cutting on all sides: straight, no burrs; the large plasma cutting machine is well formed,

What is the difference between bimetal wear-resistant steel plate and hardened wear-resistant steel plate?

1. Definition:   ⑴Bimetal wear-resistant steel plate refers to the composite high-alloy wear-resistant layer on the substrate of ordinary steel plate by hardfacing method, combining the wear-resistant performance of the wear-resistant layer and the load-bearing, deformability and weldability of the substrate. The hardness of the wear-resistant layer is generally between HRC52-64.
