Super Duplex Steel UNS S32750 Flange

Super Duplex Steel UNS S32750 Flanges are part of the duplex steel family. The microstructure of these flanges is a mix of austenitic and ferritic grades. The key distinction is that these flanges include more chromium and molybdenum. This has a higher level of corrosion resistance than regular grades. It has a dual phase microstructure that combines high strength with low corrosion resistance, making it ideal for use in chloride-rich settings.

Product Introduction

Super Duplex Steel S32750 Flanges are of higher graduation as compared to other duplex flanges. The alloy is strong and pitting-resistant. Flanges are basically attachments used in piping and tubing. It needs to be sealed and bolted strongly to make the machines accurate. Super Duplex Steel S32750 Flanges exhibit a mixed austenitic and ferritic microstructure. The key difference is that these flanges contain more chromium and molybdenum. Compared to standard grades, this provides better corrosion-resistant properties. It possesses a dual-phase microstructure that combines high strength with cost-effective corrosion resistance, specifically in chloride-rich settings.
