Key Features

• Dual-phase ferrite-austenite structure, combining high strength and outstanding corrosion resistance
• Superior resistance to inorganic acid, alkali solution, chloride ions and pitting/crevice corrosion
• Good abrasion resistance and cavitation resistance, suitable for stirring and flowing medium conditions
• Dense forged structure, higher mechanical stability and fatigue resistance than castings
• Reliable performance under medium temperature and high-pressure working conditions
• Good machinability and weldability for on-site assembly and maintenance
