Applications
• Aerospace industry: compressor discs.
• Marine and land-based machines.
• Fasteners or diverse components requiring a particularly high yield strength and which must also be stainless or non magnetic.
Mechanical properties
Precipitation hardened, nickel-based superalloy with:
• Good resistance to high temperature oxidation.
• Excellent mechanical properties up to temperatures around 700°C.
• Generally used for parts working within the 600-700°C range.
