Heat- and Creep-Resistant Austenitic Alloy
- Therma Alloy 800T / EN 1.4959 / UNS N08811 & EN 1.4876 / UNS N08810
Our Therma Alloy 800T stock material is certified for both EN 1.4959 / UNS N08811 and EN 1.4876 / UNS N08810, ensuring compliance and flexibility for demanding high-temperature environments. These stabilized austenitic alloys are designed for long-term performance, with excellent resistance to carburization, oxidation, and other types of high-temperature corrosion. Controlled grain size and optimized aluminum and titanium levels provide superior creep strength above 700 °C.
