Hastelloy S Chemical Composition
Hastelloy S Material Properties Overview
As a manufacturer and supplier in China, Arialloy supplies competitively priced hastelloy S products for industrial purchasing requirements.
Hastelloy S (UNS N06635) is a nickel alloy containing chromium and molybdenum that combines thermal stability, resistance to oxidation and good fabricability. Its nominal composition includes approximately 16% chromium and 15% molybdenum, with nickel forming the balance. Chromium contributes to surface protection against oxidation, while molybdenum provides strengthening through solid solution effects. A small addition of lanthanum improves oxidation resistance. The alloy also contains minor amounts of aluminum, silicon and manganese. Low thermal expansion and resistance to thermal fatigue are important characteristics, helping the material accommodate repeated temperature changes while maintaining useful strength and ductility. This combination supports dimensional stability during repeated heating and cooling over extended periods of exposure.
The alloy can be processed by hot working and cold forming, with intermediate annealing used when necessary to restore ductility. Gas tungsten arc and gas metal arc welding are suitable joining methods. Matching hastelloy S filler metal produces weld deposits that combine thermal stability, low thermal expansion and resistance to oxidation during exposure to elevated temperatures.
Wrought hastelloy S products are normally supplied after solution annealing at approximately 1066°C, followed by cooling in air or hydrogen.
Hastelloy S Corrosion Resistance
Hastelloy S resists oxidation and several forms of attack at elevated temperatures. Comparative laboratory tests demonstrate resistance to nitriding, carburization and hot corrosion, although performance depends on temperature, exposure duration and atmosphere.
In flowing air at 982°C for 1,008 hours, with weekly cooling to room temperature, measured metal loss was approximately 0.005 mm, with combined metal loss and internal penetration of approximately 0.012 mm. These results reflect specific laboratory exposure conditions; resistance to aqueous acids or chloride solutions requires separate evaluation for the specified medium.
Hastelloy S Mechanical Properties
In the solution annealed condition, hastelloy S plate typically exhibits a room temperature tensile strength of 849 MPa and a 0.2% offset yield strength of 383 MPa, together with 55% elongation. These values represent plate thicknesses of 9.5 to 25.4 mm and illustrate the material’s combination of strength and ductility.
Hastelloy S Temperature Characteristics
Hastelloy S offers oxidation resistance up to approximately 1093°C, together with low thermal expansion and good resistance to thermal fatigue. It retains useful strength and ductility after aging between 427°C and 871°C, although the exact response depends on exposure temperature and duration.
Its mean thermal expansion coefficient is approximately 13.3 µm/m°C between 20°C and 538°C, increasing to 14.9 µm/m°C between 20°C and 871°C. These characteristics help limit dimensional changes from expansion during thermal cycling. Resistance to oxidation does not establish the allowable temperature under mechanical loading.
