VT machining offers CNC Tapping for Incoloy 800 (UNS N08800 / 1.4876), typically supplied annealed. Fe-Ni-Cr alloy for oxidation and carburisation resistance.
CNC Tapping Notes for Incoloy 800
Incoloy 800 is tapped with cut taps (spiral-point for through holes) and controlled rigid-tapping speed; thread milling is used where tap breakage would be costly.
For estimating, a 100 × 100 × 10 mm block of Incoloy 800 weighs about 0.79 kg.
Starting Parameters for CNC Tapping Incoloy 800
