Technical FAQs — Duplex 2304 MTC Certificate
Why is Duplex 2304 considered a "Lean Duplex" on this MTC?
Duplex 2304 (UNS S32304) is classified as a "lean" duplex stainless steel because it contains very little Molybdenum (0.05 - 0.60%) and lower Nickel levels compared to standard duplex grades like 2205. The MTC chemistry confirms this cost-effective composition, which still provides high yield strength and excellent resistance to stress corrosion cracking (far superior to 304L/316L).
What heat treatment methodology is tracked on this certificate?
The MTC logs a Solution Annealing phase followed by a rapid Water Quench. For all duplex stainless steels, a fast quench is absolutely critical to avoid the precipitation of detrimental intermetallic phases and to maintain the proper two-phase (ferrite-austenite) microstructure.
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.
