ISO S — Superalloys & Titanium · S10
S10 — Titanium alloys (Ti-6Al-4V)
Hardness range: 320–380 HB. Part of the ISO S — Superalloys & Titanium group. Superalloys and titanium are the most challenging ISO group: low thermal conductivity concentrates heat at the cutting edge, and high strength persists at elevated temperatures. High-pressure coolant (70–100 bar) is mandatory. Low Vc, consistent DOC, and sharp geometry are non-negotiable. Tool life is short — plan changeovers.
