High-Temperature Performance
Oxidation Resistance
Excellent resistance to air oxidation at temperatures up to 1150°C. Forms a thin, highly adherent protective oxide layer that provides reliable protection even under cyclic conditions.
Elevated Temperature Strength
Maintains high structural strength above 500°C up to approximately 900°C, outperforming alternatives like Grade 310.
Fabrication & Processing
Heat Treatment
Solution treatment recommended at 1050-1150°C with rapid cooling. Maximum creep strength achieved after 10-20% cold work followed by solution treatment.
Welding
Excellent weldability using all standard fusion methods with matching filler metals. Pure argon shielding gas required for optimal results.
