Precipitation-hardenable nickel-cobalt-chromium grade, Alloy 105 is ideal for high temperature service.

• Turbine blades
• Turbine discs
• Turbine shafts
• Forgings
• Rolled rings
• Bolts and fasteners

Alloy 105 has excellent heat resistant properties, high strength and excellent oxidation resistance. The high creep-rupture properties of Alloy 105 makes the alloy perfect for critical gas turbine applications.

Alloy 105 can be heat treated as followed;

For optimum long term creep and ductility at 850-950°C:
4 hours at 1150°C, 16 hours at 1050-1065 °C and 16 hours at 850°C with air cooling after all heat treatment operations.

Where tensile strength, elongation and impact stength are more critical at temperature up to 700°C:
4 hours at 1125°C and 16 hours at 850°C with air cooling after all heat treatment operations.
