Inconel 625
DESCRIPTION
Inconel 625, AMS 5666, UNS N6625,Chinese GH3625 is a nonmagnetic, corrosion and oxidation-resistant, nickel-based alloy. Its outstanding strength and toughness in the temperature range cryogenic to 2000°F (1093°C) are derived primarily from the solid solution effects of the refractory metals, columbium and molybdenum, in a nickel-chromium matrix. The alloy has excellent fatigue strength and stress-corrosion cracking resistance to chloride ions. Some typical applications for alloy 625 have included heat shields, furnace hardware, gas turbine engine ducting, combustion liners and spray bars, chemical plant hardware, and special seawater applications.

HEAT TREATMENT
Alloy 625 has three basic heat treatments:
SPECIFICATION
(1)High Solution Anneal - 2000/2200°F (1093/1204°C), air quench or faster.
(2)Low Solution Anneal - 1700/1900°F (927/1038°C), air quench or faster.
(3)Stress Relieve - 1650°F (899°C), air quench.
The time at the above temperatures depends on volume and section thickness. Strip, for example, would require shorter times than large sections. Temperatures for treatments No. 1 and 2 are generally held for 1/2 to 1 hour, 1 to 4 hours for treatment No. 3.
Forgings,Sheet /Plate, Bar/Rod, Wire,Ring.
