Its innovative composition incorporates:
- Nickel (Ni): ≈24% (enhances corrosion resistance and stability)
- Chromium (Cr): ≈20% (provides excellent oxidation resistance and general corrosion protection)
- Molybdenum (Mo): ≈6.5% (boosts resistance to pitting and crevice corrosion)
- Nitrogen (N): Added to enhance strength and corrosion resistance without increasing carbon content
- Low Carbon (C): ≤0.03% (minimizes sensitization and intergranular corrosion risk)
Similar Grades:
- UNS N08367 (USA), Alloy AL-6X (generic), 1.4501 (similar but not equivalent DIN grade)

Production Processes
AL6XN round bars are meticulously crafted through:
Melting & Casting:
- Utilizes advanced melting techniques such as vacuum induction melting (VIM) or electric arc melting (EAF) to ensure high purity.
- Continuous casting or ingot casting processes followed by hot rolling to form initial billets.
Thermal Processing:
- Hot working at temperatures between 1100°C and 1250°C (2012°F to 2282°F) to shape and size the material.
- Solution annealing treatment at 1010°C to 1150°C (1850°F to 2102°F) followed by rapid cooling to optimize microstructure.
Finishing:
- Cold drawing, grinding, or polishing to achieve the desired surface finish and dimensional accuracy.
