Technical FAQs — AL-6XN MTC Certificate
Why are Molybdenum, Nitrogen, and Nickel highlighted on this MTC?
AL-6XN (UNS N08367) is a "super austenitic" stainless steel. The MTC explicitly verifies its high levels of Molybdenum (6-7%) and Nitrogen (0.18-0.25%), which work together to provide exceptional resistance to chloride pitting and crevice corrosion. Additionally, the elevated Nickel content (23.5-25.5%) ensures excellent resistance to chloride stress corrosion cracking, surpassing that of grades like 316L and 317L.
What heat treatment methodology is tracked on this certificate?
The MTC logs a Solution Annealing phase followed by a rapid Water Quench to prevent the precipitation of intermetallic phases (like sigma phase) that can severely degrade the alloy's toughness and extreme corrosion resistance.
Are the materials free from radioactive contamination?
Yes, the document strictly states that the material is free from radioactive contamination and undergoes a 100% visual inspection to ensure it is free from defects.
