Super Duplex (UNS S32760 F55) Round Bars Supplier in India

Super Duplex (UNS S32760 F55) Round Bars Supplier in India

When the environment turns aggressive – think seawater, chemical plants, and offshore oil rigs – Super Duplex (UNS S32760 F55) Round Bars step up where conventional alloys fail. Built for the harshest operational conditions, F55 bars offer an unbeatable combination of strength, corrosion resistance, and longevity.

As a trusted Super Duplex (UNS S32760 F55) Round Bars supplier in India, we deliver quality bars in a range of sizes and finishes, ready to support high-pressure, high-chloride, and high-fatigue applications. With our tested, certified stock, your critical infrastructure is in good hands.

Why Super Duplex (UNS S32760 F55) Round Bars Are the First Choice for Demanding Environments

Engineered with elevated chromium, molybdenum, and nitrogen content, Super Duplex S32760 (also known as F55) is a premium-grade stainless steel known for its outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-laden or acidic conditions.

Some of the top industries using Super Duplex F55 bars include:

  • Marine & Offshore – seawater piping, mooring chains, heat exchangers

  • Oil & Gas – risers, downhole tools, manifold blocks

  • Chemical Processing – high-pressure vessels, scrubbers, filtration systems

  • Desalination Plants – reverse osmosis systems, evaporators, brine tanks

The microstructure of Super Duplex combines both austenitic and ferritic phases, resulting in superior mechanical properties, nearly double the strength of 300-series stainless steel, and unmatched corrosion resistance – making it a material of choice for aggressive operational setups.

We supply bars in custom-cut lengths, rough turned, polished, or peeled finishes, backed by MTCs and optional third-party inspections.
