UNS NO32760 (F55) Pipe
UNS S32760 (F55) Pipes are manufactured, stocked, and exported by Rose Metal Industries, a trusted name in the stainless steel and super duplex industry. These pipes are designed for high-performance applications where superior corrosion resistance and mechanical strength are critical. Rose Metal Industries ensures that all F55 pipes meet international quality standards and are supplied across India and globally, particularly catering to industrial hubs in Tamil Nadu, Andhra Pradesh, Karnataka, Telangana, Puducherry, and the Andaman & Nicobar Islands..
The chemical composition of UNS S32760 (F55) pipes includes 24–26% Chromium (Cr), 6–8% Nickel (Ni), 3–4% Molybdenum (Mo), 0.2–0.3% Nitrogen (N), with low Carbon ≤0.03%, along with trace amounts of Silicon, Manganese, Phosphorus, Sulfur, and sometimes Copper or Tungsten. This unique composition gives F55 pipes exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, making them ideal for harsh environments such as marine, chemical, and offshore applications. The dual-phase austenitic-ferritic microstructure further enhances both corrosion resistance and mechanical strength..

Mechanically, UNS S32760 pipes offer yield strength around 550 MPa, tensile strength 750–800 MPa, elongation ≥25%, and hardness up to BHN 270–310, depending on pipe thickness and heat treatment. These mechanical properties allow for high-pressure and high-temperature applications while maintaining reliability and long service life. F55 pipes are also known for excellent weldability, toughness, and fatigue resistance, which is critical in industrial and offshore environments..
Rose Metal Industries provides F55 pipes in various forms including seamless and welded pipes, with different diameters, wall thicknesses, lengths, and custom finishes to meet specific project requirements. The pipes comply with ASTM A789 / A790, ASTM A312, ASTM A213, ASME, and EN 1.4501 standards. Mill Test Certificates (MTC), chemical analysis reports, and third-party inspection can also be provided to ensure traceability and quality assurance.
