Exotic Alloys Alloy A286 Pipes Overview
Zeon Exports supplies Exotic Alloy A286 (UNS S66286) tubing, an iron-nickel-chromium precipitation-hardening superalloy combining high strength with good oxidation resistance up to 704°C.
Exotic Alloy A286 Tubing is used in gas turbine, aerospace and high-temperature instrumentation systems. Its titanium-driven precipitation hardening gives high tensile and yield strength while retaining good oxidation resistance in continuous service up to 704°C, making it a preferred choice wherever standard stainless steel lacks sufficient high-temperature strength.
- Age-hardened via titanium for very high strength
- Tensile ≥895 MPa, yield ≥655 MPa in Class A condition
- EN 10204 3.1 certified, export-ready worldwide
