Q: What distinguishes Hastelloy N10665 from other nickel alloys?

A: N10665 exhibits superior corrosion resistance in reducing chemical environments due to its high molybdenum content (26-30%), while maintaining excellent fabricability. Unlike many high-temperature alloys, it doesn't require precipitation hardening treatments.

Q: Can these plates be used in rocket propulsion systems?

A: Yes, they are suitable for combustion chambers, nozzles, and fuel system components where resistance to hot gaseous hydrochloric acid is required. Actual suitability depends on specific operating parameters.

Q: What surface finishes are available?

A: Standard mill finish is supplied, with optional pickled, ground, or polished surfaces available upon request. Surface roughness can be customized to Ra ≤ 0.8μm.

Q: How does thermal cycling affect dimensional stability?

A: The alloy's low coefficient of thermal expansion (9.6 μm/m·°C at 20-100°C) minimizes dimensional changes during repeated heating/cooling cycles, critical for precision aerospace assemblies.

Q: What quality documentation is provided?

A: Each shipment includes material certification, chemical analysis reports, mechanical test results, and non-destructive testing records. Additional certifications can be discussed.
