- Chemical Composition:
- Ni (24.0–27.0%), Cr (13.5–16.0%), Fe (balance), with Mo (1.0–1.5%), Ti (1.9–2.35%), and Al (≤0.35%) for enhanced stability35.
- Mechanical Properties:
- High-Temperature Strength: Tensile strength up to 1250 MPa, yield strength 650–800 MPa at 650°C12.
- Oxidation Resistance: Forms a protective Cr₂O₃ layer, effective up to 1300°F (704°C)13.
- Creep Resistance: Maintains structural integrity under prolonged stress at elevated temperatures25.
- Heat Treatment:
- Solution annealing at 980–1000°C followed by aging at 700–720°C to achieve peak hardness and stress rupture resistance56.
Advanced Processing Capabilities
Incoloy A-286 round bars are engineered for precision manufacturing:
- Hot Working: Forge at 900–1140°C with post-process annealing to refine grain structure26.
- Cold Working: Intermediate annealing at 700–750°C required to relieve stress during forming23.
- Welding: Compatible with TIG/MIG methods using AWS ERNiCr-3 filler; pre-solution treatment minimizes cracking26.
- Machining: Use carbide tools with low cutting speeds to counteract work hardening25.
