Product Performance Highlights
Superior High-Temperature Stability:
- Maintains excellent oxidation resistance and mechanical strength up to 700°C, with proven stability in continuous service at 1,100°C12.
- Resists thermal fatigue and creep deformation in extreme heat5.
Outstanding Corrosion Resistance:
- Resists chloride stress corrosion cracking, organic acids (acetic, formic), and nuclear-grade high-purity water23.
- Performs exceptionally in both oxidizing and reducing atmospheres35.
Excellent Fabricability:
- Easily welded via TIG, MIG, or resistance welding methods; post-weld annealing (870°C/1h) eliminates stress36.
- Suitable for cold/hot working, forging, and machining into complex shapes13.
Production Methods
Inconel 600 round bars are manufactured through precision processes36:
- Vacuum Induction Melting (VIM):
- High-purity raw materials are melted under controlled conditions to minimize impurities.
- Hot Rolling & Forging:
- Ingots are hot-rolled or forged into billets to refine grain structure and enhance mechanical properties.
- Cold Drawing/Finishing:
- Cold-drawn to achieve tight dimensional tolerances and smooth surface finishes.
- Solution Annealing:
- Heated to 1,050–1,100°C and rapidly cooled to optimize corrosion resistance and ductility.
Equivalent Grades & Standards
- UNS N06600
- ASTM B168, AMS 5540, DIN 2.4816
