Super Duplex Steel S32760 Paddle Blank Flanges from Ratna Exports are a reliable option because of their exceptional corrosion resistance and high strength. For demanding industrial settings where durability is important these flanges are ideal. The alloy performs exceptionally well in demanding conditions thanks to its chemical composition which includes 24–26% chromium, 3–4% molybdenum, 6–8% nickel and 0.20–0.30% nitrogen. Our flanges are available in standard sizes and are widely used where tight isolation and safety are critical. We supply Super Duplex S32760 Flanges at competitive prices to meet diverse customer needs.
These paddle blanks stand up well against harsh chemicals and stress corrosion, even in high-temperature settings. Their excellent high-temperature strength, oxidation resistance, and cracking resistance make them ideal for long-term service. The flanges maintain strength even when exposed to elevated heat, thanks to their high melting point of 1350°C (2460°F). Every product undergoes strict testing, including PMI, spectro analysis, tensile testing, elongation, and IGC tests. You also get assurance of pitting resistance a must in chloride-heavy operations.
The flanges are easy to work with during fabrication. They offer good weldability and form well at hot-working temperatures between 1600°F to 2200°F. Since they don’t harden quickly, there’s less chance of cracking while welding or machining. The sizes are customized for different dimensional requirements and range from ½” to 48″. To guarantee a safe delivery, these flanges are also provided with the appropriate marking, paperwork, and safe packaging.
Our Super Duplex 32760 Paddle Blank Flanges are used in petrochemical, nuclear, power generation, and marine industries. They’re commonly seen in heat exchangers, pressure vessels, instrumentation parts, casings, and reactor systems. Every piece is made to meet international standards and shipped with required test certifications. If you’re looking for strong and corrosion-proof spacer or spectacle blind flanges, we’re ready to help. Contact us today for bulk availability or specific size need.
