Description (English)
Hastelloy C-22 (UNS N06022, DIN 2.4602) is the premium nickel superalloy for tablet press upper punches and capsule filler tamping pins processing corrosive pharmaceutical formulations such as potassium chloride, effervescents and acidic or hygroscopic powders. With a PREN of ≈ 66 — higher than C-276 — C-22 keeps cup tips and pin heads clean, non-sticking and contamination-free where D2 and 440C tooling pits and builds up powder films within days. Vertex Alloy supplies solution-annealed C-22 ground bars from 2 to 120 mm (including 2–12 mm tamping pin grinding stock, h7/h8) to ASTM B574 with EN 10204 3.1 certificates, plus custom-machined finished upper punches and tamp pins per drawing for all major press and encapsulator brands (Fette, Korsch, Bosch GKF, IMA, MG2 and more). Full heat-number traceability from mill bar to finished tooling.
