- Check the Chemical Composition
The first step in verifying genuine UNS S32205 material is analyzing its chemical composition. Authentic Super Duplex UNS S32205 must contain:
- Chromium (Cr): 22.0 - 23.0%
- Nickel (Ni): 4.5 - 6.5%
- Molybdenum (Mo): 3.0 - 3.5%
- Nitrogen (N): 0.14 - 0.20%
- Carbon (C): ≤0.03%
- Other elements like Mn, Si, P, and S in trace amounts
Laboratory testing or portable spectrometers can confirm these chemical properties.
- Verify Mechanical Properties
Genuine Super Duplex UNS S32205 material exhibits excellent mechanical properties, including:
- Tensile Strength: 620 MPa (min)
- Yield Strength: 450 MPa (min)
- Elongation: 25% (min)
- Hardness: ≤10 HV
Comparing these values with the supplier’s test certificates ensures authenticity.
- Perform Corrosion Resistance Testing
Super Duplex UNS S32205 has superior corrosion resistance, particularly against pitting and crevice corrosion. Conducting ASTM G48 or similar corrosion tests can help confirm its resistance to aggressive environments, making it ideal for marine and offshore applications.
- Compare with 316L Stainless Steel
One way to identify genuine UNS S32205 material is by comparing it with 316L stainless steel. UNS S32205 offers:
- Twice the strength of 316L
- Higher resistance to chloride stress corrosion cracking
- Enhanced durability in harsh environments
- Source from Reliable Suppliers
To ensure authenticity, always purchase from reputable Super Duplex Steel Suppliers like Krystal Global Engineering Limited. Check supplier certifications, test reports, and industry approvals.
- Verify Markings and Certification
Authentic UNS S32205 material should have clear markings, including:
- Grade & standard (e.g., Duplex 2205, SAF 2205)
- Manufacturer’s name/logo
- Heat number & batch number
- Mill test certificate (MTC)
Identifying genuine Super Duplex UNS S32205 material is essential for ensuring quality and performance. By checking chemical composition, mechanical properties, corrosion resistance, and sourcing from certified suppliers, you can avoid copyright materials.
