Density: Approximately 7.8 g/cm³.
Coefficient of Thermal Expansion: 11.3 × 10⁻⁶/℃ between 20℃ and 100℃.
Thermal Conductivity: 11.3 W/(m·K) at 20℃, 21.2 W/(m·K) at 597℃.
Specific Heat: 0.44 J/(kg·℃) at 20℃, 432 J/(kg·℃) at 246℃.
Resistivity: 0.44 Ω·mm²/m.

 

Solution treatment: 920-1150℃ followed by rapid cooling to achieve a non-magnetic austenitic structure.
Annealing: 750-850℃ followed by slow cooling to reduce hardness and increase ductility. Quenching and Tempering: Quenching temperatures are 950-1050℃, and tempering temperatures are 600-700℃ to optimize strength and toughness.

 

Good Corrosion Resistance: High chromium and nickel contents enable excellent performance in a variety of corrosive environments.
High Strength and Toughness: High tensile strength and yield strength while maintaining good ductility and toughness.
Processing Properties: Excellent cold working and weldability.
Intergranular Corrosion Resistance: Ultra-low carbon content reduces the risk of intergranular corrosion.
