Compare UNS S32750 and S32760 super duplex stainless steels, including chemical composition, F53 vs F55, PREN, corrosion resistance, applications and material selection.

S32760 Super Duplex Stainless Steel, also known as UNS S32760 (Zeron 100), is a high-performance alloy specifically developed for extreme corrosive and high-stress environments. Featuring a balanced austenitic–ferritic microstructure, S32760 delivers an outstanding combination of high mechanical strength and superior corrosion resistance.

Blind Flanges are solid, disc-shaped flanges used to close the ends of piping systems, valves, or equipment nozzles. They are commonly applied in systems where access to the pipeline is not required, for pressure testing, or to isolate sections of the pipeline. Known for their simplicity, strength, and ability to withstand high pressure, Blind Flanges are widely used in chemical, water, gas, and oil pipelines, as well as in high-pressure or high-temperature applications.

Lap Joint Flanges (LJ flanges) are commonly used in piping systems that require frequent disassembly, servicing, or alignment adjustments. Known for their two-piece design — a forged backing flange paired with a Lap Joint Stub End — LJ flanges offer outstanding flexibility during installation and are widely used in stainless steel, corrosion-resistant, and sanitary applications.

Socket Weld Flanges (SW flanges) are widely used in small-diameter, high-pressure piping systems, especially where superior leakage integrity and excellent fatigue performance are required. Known for their structural strength and clean internal weld profile, SW flanges are commonly used in high-pressure steam, chemical processing, hydraulic systems, instrumentation lines, and refinery services.
