Performance Characteristics
Physical Properties
Density: 8.4g/cm³
Melting Point: 1374-1420℃
Mechanical Properties
Tensile Strength at Room Temperature: ≥685MPa
Elongation at Room Temperature: ≥30%
Oxidation Resistance: Oxidation rates at 900℃, 1000℃, 1100℃, and 1200℃ are 0.0535g/(m²・h), 0.1560 g/(m²・h), 0.3905 g/(m²・h), and 0.5810 g/(m²・h), respectively.
Process Properties
Hot Working Properties: Hot working temperature range is 1149℃-982℃. Forging, hot rolling, and extrusion are possible.
Cold Working Properties: Drawing, cold rolling, and cold extrusion are possible, but excessive cold working should be avoided to prevent brittleness and cracking.
Welding Properties: Excellent weldability. TIG welding, spot welding, seam welding, or brazing are possible. ERNiCr-3 welding wire is recommended.
