Applications
Widely used in automotive lighting,
computer displays,
camera lenses,
mobile phone components,
and other transparent parts and optical equipment components.
Features
- Machines 10 to 15 percent faster than P20
- Pre-hardened to 38-42 HRC
- Uniform microstructure & hardness (40 HRC between surface & interior)
- Never needs stress relieving
- Highly weldable, HAZ gets softer not harder (re-age harden to bring back to 40 HRC)
- EDM layer is easy to remove
Cutting:
Precision cutting to standard dimensions
Custom cutting according to client specifications
Surface Grinding/Polishing:
Thickness tolerance: -0 to +0.1mm
Flatness: 0.01/100mm
Surface roughness: Ra ≤1.6 or Rz ≤6.3
