To ensure stable quality,our factory execute strict quality inspection during our entire process :

1. Material Test: use spectrometer inspection to verify chemical composition , ensure alloy elements like carbon, chromium and manganese meet standard.

2. Hardness Test: adopt random Rockwell hardness test,ensure uniform hardness for cutting edge and end bits and working surface reaches required hardness while maintaining proper toughness to avoid brittle fracture.

3. Dimension Inspection: we will check overall length, thickness, bolt hole pitch and bevel angle, and control tolerance within industrial standard.

4. Visual & Magnetic Particle Inspection: no cracks, porosity or laminations. No chipping on cutting edge and no burrs around bolt holes.

5. Sampling Impact Test: our technician will simulate working impact to verify anti-breakage performance.
