Key Features of S32760 Super Duplex Stainless Steel
S32760 duplex steel provides superior resistance to chloride corrosion, high thermal conductivity, and low thermal expansion. The enhanced chromium, molybdenum, and nitrogen content deliver exceptional resistance to pitting, crevice corrosion, and other corrosive attacks.
This alloy demonstrates resistance to various inorganic and organic acids. The addition of copper enhances resistance to non-oxidative acid corrosion. S32760 also withstands strong alkaline corrosion, though prolonged exposure above 300°C is not recommended as it may reduce material toughness.
Originally developed in the 1980s to address corrosion resistance limitations in second-generation duplex stainless steels, S32760 has evolved into a critical material for pipeline systems, oil and gas development, seawater environments, flue gas desulfurization, desalination, and chemical applications.
The inclusion of tungsten and copper enhances corrosion resistance in specific acids and improves passivation capabilities in seawater environments. The microstructure features a balanced α/γ phase ratio under proper solid solution conditions, though careful thermal processing is required to prevent precipitation of intermetallic phases.
Applications of S32760 Super Duplex Stainless Steel
- Neutral chloride environments
- Oil refining industry equipment
- Chemical industry pipelines
- Oil and gas industry components
- Pulp and paper manufacturing
- Fertilizer industry applications (urea, phosphate)
- Seawater environments and energy conservation systems
- Food and pharmaceutical industry equipment
