Product Description
Zeron 100 (commonly designated under UNS S32760 or Werkstoff Nr. 1.4501) is a premium super duplex stainless steel designed for highly aggressive corrosive environments. Known for its 50/50 mixed microstructure of austenite and ferrite, it offers far superior strength and corrosion resistance compared to standard austenitic or standard 2205 duplex stainless steels.
What makes Zeron 100 distinct from standard super duplex alloys (like 2507) is its intentional addition of copper and tungsten, which significantly improves its performance in hot chloride and sour gas environments.
Technical Profile
1. Chemical Composition (Wt%)
The specific addition of copper and tungsten gives Zeron 100 an edge in non-oxidizing acids.
| Element | Min % | Max % |
| Chromium (Cr) | 24.0 | 26.0 |
| Nickel (Ni) | 6.0 | 8.0 |
| Molybdenum (Mo) | 3.0 | 4.0 |
| Copper (Cu) | 0.50 | 1.00 |
| Tungsten (W) | 0.50 | 1.00 |
| Nitrogen (N) | 0.20 | 0.30 |
| Iron (Fe) | Balance | Balance |
2. Key Mechanical Properties (Typical Room Temp)
-
Tensile Strength: $ge 750 text{ MPa}$ ($109 text{ ksi}$)
-
Yield Strength (0.2% Offset): $ge 550 text{ MPa}$ ($80 text{ ksi}$)
-
Elongation: $ge 25%$
-
Hardness: Max 28 HRC (NACE MR0175 compliant for sour service)
3. Pitting Resistance Equivalent Number (PREN)
Zeron 100 guarantees a high PREN, confirming its resistance to localized pitting corrosion:
$$text{PREN} = % text{Cr} + 3.3(% text{Mo} + 0.5% text{W}) + 16(% text{N}) > 40$$
Notable Characteristics & Advantages
-
Exceptional Crevice & Pitting Resistance: A guaranteed PREN greater than 40 ensures excellent performance in seawater pipelines and desalination units.
-
High Mechanical Strength: Roughly twice the yield strength of 300-series austenitic stainless steels, allowing for weight savings via thinner walls or smaller bar diameters.
-
Sour Service Performance: Superior resistance to stress corrosion cracking (SCC) in hydrogen sulfide ($H_2S$) containing fluids.
-
Erosion-Corrosion Resistance: High hardness and tensile properties yield superior resistance to fluid wear compared to conventional steels.
Typical Engineering Applications
-
Oil & Gas Industry: Subsea piping manifolds, downhole equipment, Christmas trees, and sour service transport lines.
-
Marine & Desalination: High-pressure RO (Reverse Osmosis) piping, pump shafts, seawater cooling systems, and propellers.
-
Chemical Processing: Equipment dealing with hot nitric, sulfuric, or phosphoric organic acids.
-
Flue Gas Desulfurization (FGD): Scrubber systems facing high halide concentrations.
Manufacturing & Compliance Standards
Round bars are typically supplied under specifications such as:
-
ASTM A276 / A479: Standard specifications for stainless steel bars.
-
NORSOK MDS D57: Strict standard for petroleum industry applications.
-
NACE MR0175 / ISO 15156: Materials for use in $H_2S$-containing environments in oil and gas production.
