High-temperature Performance
At 700℃, the tensile strength remains above approximately 400 MPa. At 900℃, the tensile strength remains above approximately 120 MPa.
Long-term operating temperature range
For antioxidant and anti-carburization applications, the recommended long-term operating temperature range is 700°C to 1150℃
Maximum intermittent temperature resistance: Up to 1200℃.
Antioxidant properties: At 1200°C in static air, the oxidation rate is extremely low, the oxide film has strong adhesion, and exhibits excellent spallation resistance.
Creep resistance: At 700–900℃ and under moderate stress, its creep resistance is superior to that of most austenitic stainless steels.
