Information

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,

Intrinsic quality

1. Wear-resistant layer thickness: Measured after polishing, the hardfacing layer is obvious, take multi-point measurement and average value;

2. The total thickness of the steel plate: controlled within the allowable range, ±0.5mm

3. Hardness: within the required range, HRC55-62

4. Composition: alloy composition;

5. Metallography: Metallographic analysis;
