01 The "Micro-Chaos" Diagnosis
Incident Report
Client reported random tool breakage and porcelain chipping on long-span bridges. Metallurgical analysis of the previous supplier's discs revealed inconsistent grain size (ASTM G5 to G9 variance) within the same batch. This created "hard spots" that shocked the milling spindle.
The ValidTi Intervention: We replaced the stock with ValidTi PRO (Grade 23 ELI) featuring controlled Triple-Melting and Equilibrium Cooling.
- ✓ Equiaxed Grain Structure (G10+)
- ✓ Alpha-Case Depth: 0.00mm
