Chemical Composition:
Ni (~69%), Cr (18-21%), Al (1.0-1.8%), Ti (1.8-2.7%), with trace elements like B and Co for enhanced stability37.
Mechanical Properties:
Tensile Strength: 1250 MPa | Yield Strength: 780 MPa | Elongation: 30% (annealed condition)35.
High-Temperature Performance: Maintains structural integrity up to 815°C (1500°F) with minimal creep deformation45.
Physical Properties:
Density: 8.19 g/cm³ | Melting Point: 1405°C | Non-magnetic, ideal for critical electrical applications
Nimonic 80A round bars are engineered for precision manufacturing in demanding industries:
- Machining:
- Compatible with conventional techniques (turning, milling), but requires low cutting speeds to counteract work hardening38.
- Hot/Cold Working:
- Hot forming: Recommended at 900–1100°C followed by solution annealing (1080°C/air cooling)37.
- Cold forming: Intermediate annealing at 700–750°C to relieve stress67.
- Welding:
- TIG/MIG welding with matching filler metals (e.g., AWS ERNiCr-3); pre-solution treatment minimizes cracking37.
- Heat Treatment:
- Solution annealing (1080°C) + aging (700°C for 16h) to achieve peak hardness and corrosion resistance36.
