Density: 8.1 g/cm³ | Melting Point: 1320-1390℃ | Tensile Strength: 650 MPa | Yield Strength: 295 MPa | Elongation: 35%
Incoloy 926 demonstrates superior performance in corrosive environments, particularly in halide media and acidic conditions containing H2S. Its exceptional resistance to pitting, crevice corrosion, and chloride ion stress corrosion cracking makes it ideal for demanding applications.
- Marine engineering and seawater purification systems
- Chemical processing equipment
- Oil and gas extraction
- Flue gas desulfurization systems
- Phosphoric and sulfuric acid production
- Cellulose pulp production
- Fire protection systems
Incoloy 926 can be processed through cold, hot, and machining methods, though its high strength requires powerful equipment. Workpieces must remain clean during heat treatment, avoiding contact with low-melting-point metals.
Temperature range: 1150℃-1200℃ (optimal at 1170℃) | Cooling method: Water quenching for materials >1.5mm thickness, rapid air cooling for thinner materials
