General Characteristics of Incoloy™ 825
Incoloy™ 825 withstands chloride-iron stress-corrosive cracking, pitting and crevice attack. This is a nickel-chromium-iron alloy with molybdenum, copper and titanium that resists corrosion from oxidation and reducing media. Incoloy™ 825 is readily machinable and offers exceptional fabricability and weldability.

Heat Treatment of Incoloy™ 825
Anneal between 1700° and 1800°F (927° to 982°C)
1800°F (982°C) anneal maximizes softness and fine grain structure without sacrificing corrosion resistance
1725°F (941°C) optimum stabilizing temperature
Rapid cool sections heavier than wire and sheet
Remove surface contamination before annealing
Applications of Incoloy™ 825
Equipment used to produce and handle phosphoric acid
Equipment for handling refinery and coal-washing solutions and sludge
Equipment used in the sulfuric acid pickling of copper and ferrous alloys
Paper production industry
Sour gas and oil well parts
Flue gas scrubbers
Machinability of Incoloy™ 825
Conventional machining in annealed condition
Workability of Incoloy™ 825
Hot work between 1600° and 2150°F (871° and 1177°C)
Final working between 1600° and 1800° (871° and 982°C) brings maximum corrosion resistance
Air cool; faster cooling OK depending on size of section
Well-powered, rigid equipment recommended for cold forming

Principal Design Features
One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength.
Machinability
Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening if machining in this condition.
Heat Treatment
CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.
Welding
Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.
Forging
Soak for 1 hour at 2150 F (1177 C) prior to forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.
