Heat Treatment Process for 2.4610 Forgings
All 2.4610 forgings are delivered in the improved solution annealing (ISA) condition, performed in our 10 fully automated heat treatment furnaces:
Solution Annealing — 1150–1180°C
Heat the forging to 1150–1180°C (2100–2150°F) and hold for sufficient time to completely dissolve all precipitates including sigma phase, carbides and mu phase.
Rapid Water Quench
Transfer immediately to water or polymer quench bath. The part must cool rapidly through the sensitization range (650–1000°C) to prevent chromium carbide reprecipitation and preserve full corrosion resistance.
Optional Aging (Specialty Use Only)
For higher strength applications, optional aging at 650–700°C for 4–8 hours is available. Note: aging reduces corrosion resistance — confirm with your engineer before specifying.
Time-temperature furnace charts are archived for every batch and included with the EN10204 3.1 mill test certificate, providing full heat treatment traceability for your specific forging batch.
