Product information

Grade: HAYNES 214
Origin: USA

HAYNES 214 is a nickel-chromium-aluminum-iron high-temperature alloy strengthened by solid solution. It forms a dense aluminum oxide protective layer thanks to its high aluminum content combined with a trace amount of yttrium. This oxide layer sticks really well and doesn't peel off easily in hot and cold cycles. It can maintain outstanding high-temperature oxidation resistance above 955°C for a long time and has excellent resistance to carbon penetration and corrosion from chlorine-containing flue gases. It's also very adaptable to hot and cold working processes. That's why, for decades, it's been widely used in areas with extremely high-temperature oxidation conditions, like honeycomb seals in aircraft gas turbines, high-temperature racks for heat treatment, internal parts of incinerators, ceramic firing fixtures, and components inside automotive catalytic converters.

Product parameter

Chemical composition

The nickel (Ni) content is the remainder and serves as the base matrix for HAYNES 214 alloy, stabilizing the austenitic structure and providing high-temperature toughness.
Chromium (Cr) content between 15.00%~17.00% forms an outer chromium oxide film, which helps enhance oxidation and sulfur resistance.
Aluminum (Al) content 4.00%~5.00%, core protective element, continuously formed at high temperatures, inner layer of alumina to block corrosive media.
Iron (Fe) content 2.00%~6.00%, balancing costs and improving cold and hot processing plasticity.
Yttrium (Y) content 0.002%~0.040%. Rare earth elements enhance the bonding strength of the oxide film and inhibit thermal cycling spalling.
Carbon (C) content does not exceed 0.15%, with reasonable carbon content control, balancing grain boundary strength and weldability.
Manganese (Mn) content not exceeding 1.00%, melting and deoxidation, improving hot workability.
Silicon (Si) content must not exceed 0.50%, with strict upper limit control to avoid brittle phases.
Titanium (Ti) content not exceeding 0.50%, stabilizing the structure and optimizing high-temperature environment stability.
Boron (B) content should not exceed 0.015%, refine grain boundaries, and reduce the tendency for high-temperature intergranular cracking.
Molybdenum (Mo), cobalt (Co), and tungsten (W) must not exceed 1.00%, 2.00%, and 1.00% respectively; phosphorus (P) and sulfur (S) must not exceed 0.015% and 0.015% respectively. Impurity limits are strictly limited to ensure long-term stable operation under high-temperature conditions.

Mechanical properties

Tensile strength: 800 MPa, indicating the maximum tensile force the material can withstand.
Yield strength: 440 MPa, the force at which the material begins to undergo permanent deformation.
Elongation: 28%, indicating the amount of plastic deformation the material can undergo before stretching and breaking; forming and welding processes are stable and controllable.
Hardness: 240 HB, which is the material's ability to resist hard objects pressing into its surface, with good annealed machinability.
Fatigue strength: Stable fatigue life under high-temperature cycling heat loads and alternating oxidation atmospheres, with the oxide film not prone to peeling and failure.
Elastic modulus: 218 GPa, reflecting material stiffness, minimal deformation under high-temperature forces, and excellent dimensional stability of high-temperature static components.
