General Characteristics of Hastelloy N™
A high-temperature nickel alloy, Hastelloy N™ withstands aging and embrittlement. It resists oxidation for continuous service up to 1800°F (982°C) and for intermittent service up to 1900°F (1038°C). Able to be readily fabricated, it’s ideal for high-heat applications and equipment used with hot fluoride salts.

Chemical Composition of Hastelloy N™
Carbon 0.04-0.08
Chromium 6.00-8.00
Molybdenum 15.00-18.00
Iron 5.00 max
Manganese 0.8 max
Aluminum + Ti 0.5 max
Boron 0.01 max
Sulfur 0.03 max
Nickel remainder
Heat Treatment of Hastelloy N™
Solution anneal
Heat to 2165°F (1038°C)
Soak time depends on thickness
Rapidly air cool
Applications of Hastelloy N™
Extreme heat uses
Equipment used with hot fluoride salts
Machinability of Hastelloy N™
Low cutting speeds
Use sintered carbide cutting tools and grind to 10-15 degree side rake angle and 6-7 degree side clearance for facing or turning operations
Use short drill and grind with minimum clearance to clear the work – generally about 140 degrees total – when drilling
Use sulfur-based oil coolant when drilling, or when turning, facing or boring at higher speeds
Workability of Hastelloy N™
Readily forged  between 1600°F (871°C) and 2150°F (1177°C)

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.
