Product Description
✅ Alloy composition includes elevated levels of chromium (Cr), nickel (Ni), molybdenum (Mo), and nitrogen (N), delivering exceptional resistance to pitting and crevice corrosion.
✅ Popular grades:
• 904L: Cr 19–23%, Ni 23–28%, Mo 4–5%, Cu 1–2%, N ≤ 0.10
• 254SMO: Cr 20–22%, Ni 18–20%, Mo 6–6.5%, N 0.18–0.25
• AL-6XN: Cr 20–22%, Ni 24–26%, Mo 6–7%, N 0.10–0.20
✅ Non-magnetic in annealed state; slight magnetism may occur after cold working.
✅ Applications:
• Oil & Gas: Downhole tubing, valves, pipelines
• Chemical Processing: Heat exchangers, reactors
• Marine: Saltwater-exposed components
• Pharmaceuticals: High-purity, corrosion-resistant equipment
✅ Microstructure features stabilized austenite matrix for strength, ductility, and enhanced corrosion protection.
