What Is Super Duplex Flanges?

Super Duplex Blind Flanges Werkstoff Nr 1.4410 are cost-effective and corrosion-resistant thanks to their dual-phase microstructure and high tensile strength. This alloy, exemplified in Super Duplex UNS S32750 Flanges, proves highly effective in environments with elevated chloride levels. Similar to their counterparts, these super duplex alloys offer advantages such as lower alloying costs and increased tensile and yield strength compared to similar ferritic and austenitic grades. This ensures robust resistance to equipment corrosion in environments containing chlorine. This not only offers buyers a welcomed cost advantage but also allows for the acquisition of smaller or thinner cross-sectioned Super Duplex Flanges without compromising on quality or performance.
