Hastelloy C Sheet (Plate Strip) contains a large number of elements such as Cr, Mo, and single-phase austenite. It has many excellent properties of corrosion resistant alloys have good resistance to oxidizing and moderately reducing corrosion. Hastelloy C Sheet (Plate Strip) is capable of withstanding high temperature, stress, severe corrosion and erosion prone environment. Hastelloy C
Sheet Plate Strip details will be elaborated in the following.
General Characteristics of Hastelloy C Sheet
An alloy composed of nickel, molybdenum, chromium and iron, Hastelloy C Sheet maintains its outstanding properties in extreme heat, holding its strength and resisting oxidation. It also resists chlorine and compounds with chlorine, as well as strong oxidizing acids, acid mixes and salts. One of the most corrosion-resistant alloys, Hastelloy C Sheet's exceptional in high-stress applications and in environments prone to repeated thermal shock.
Chemical Composition of Hastelloy C

0.15max | 3.75-5.25 | 4.5-7.0 | 15.5-17.5 | 16.0-18.0 | 0.20-0.40 | 1.0max | 1.0max | 0.04max | 0.03max | remainder |
Heat Treatment of Hastelloy C Sheet (Plate Strip)
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 Sheet (Plate Strip)
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 Sheet (Plate Strip)
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

Preheat to temperatures to 2200°-2250° F (1204°-1232°C)
Forge with hot working procedures:
Hammering
Pressing
Rolling
