General Characteristics of Hastelloy C™
An alloy composed of nickel, molybdenum, chromium and iron, Hastelloy™ Alloy-C maintains its outstanding properties in extreme heat, holding its strength and resisting oxidation. The alloy also resists chlorine and compounds with chlorine, as well as strong oxidizing acids, acid mixes and salts. One of the most corrosion-resistant alloys, it’s exceptional in high-stress applications and in environments prone to repeated thermal shock.

Heat Treatment of Hastelloy C™
Anneal: Heat at 2235=20 deg F for a length of time dedicated by the mass and cross section. Air cool generally to 1 to 2 hours.
Age hardening after annealing:
Hold at 1575°-1600°F (857°-871°C) for 8-10 hours
Air-cool to Rockwell C 35-40
Hold castings for 16 hours at aging temperature to achieve hardness and high yield strength (not required or suggested to resist corrosion on for strength at high temperatures).
Applications of Hastelloy C™
Combustion chambers
Heat-treating equipment
Collector rings, combustion chambers and exhaust stacks for high-heat applications in for conventional aircraft and jets
Pipe connections, pumps and valves for oil refinery, chemical and petrochemical applications
Machinability of Hastelloy C™
Can be machined at low cutting speeds
Use sintered carbide cutting tools and grind to 6-7 degree side clearance and 10-15 degree side rake angle 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 C™
Preheat to temperatures to 2200°-2250° F (1204°-1232°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.
