VT machining offers CNC 4-Axis Machining for Incoloy 825 (UNS N08825 / 2.4858), typically supplied annealed. Mo and Cu added for sulfuric and phosphoric acid resistance.
CNC 4-Axis Machining Notes for Incoloy 825
For a hard-to-cut grade like Incoloy 825, multi-axis machining reduces the number of setups, so there are fewer re-clamps and less time spent cutting.
For estimating, a 100 × 100 × 10 mm block of Incoloy 825 weighs about 0.81 kg.
