What's Inside This Duplex 2205 MTC Certificate
This sample Duplex 2205 mill test certificate mirrors the rigorous QA documentation package shipped with every high-performance austenitic-ferritic stainless steel order. It demonstrates how Ananka Fasteners reports critical metallurgical data ensuring audit-readiness and mitigating risk for chloride-rich offshore applications.
- Full Traceability: Heat and lot numbers linking each stud bolt, hex bolt, or threaded rod directly back to its original melt.
- Chemical Composition: Verification of essential elements including Chromium (22-23%), Nickel (4.5-6.5%), and Molybdenum (3-3.5%) to ensure a Pitting Resistance Equivalent Number (PREN) > 34.
- Nitrogen Enrichment: Explicit reporting of Nitrogen (N) content (0.14-0.20%) to verify structural stability and enhanced pitting resistance.
- Mechanical Properties: Verified extreme tensile strength (min 655 MPa), yield strength (min 450 MPa—more than double that of 316L), elongation, and hardness limits.

Technical FAQs — Duplex 2205 MTC Certificate
Why is Nitrogen (N) reporting critical on a Duplex 2205 MTC?
Nitrogen stabilizes the austenitic phase, increasing yield strength and resistance to localized pitting. Your MTC verifies the exact Nitrogen level to guarantee mechanical integrity.
Why choose Duplex 2205 over 316L?
Duplex 2205 offers twice the yield strength of 316L and superior resistance to chloride-induced stress corrosion cracking, making it ideal for marine environments.
