HASTELLOY C™


WHAT IS HASTELLOY C™?
Hastelloy C is 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. Hastelloy C is 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.


HASTELLOY C FORGINGS
Hastelloy has become popular because of its staggering list of achievements, but corrosion resistance remains at the top of the list. With nickel, molybdenum and chromium in the mix, Hastelloy C is highly weldable and offers tremendous heat resistance that makes it perfect for applications in seals, springs and other pieces of mechanical structures such as aerospace parts.

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, c 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)
Forge with hot working procedures:
Hammering
Pressing
Rolling
