UNS NO32760 (F55) Hexagon Rods
UNS S32760 (F55) Hexagon Rods are premium super duplex stainless steel products manufactured, stocked, and exported by Rose Metal Industries. These rods are designed for demanding applications where high strength, excellent corrosion resistance, and durability are required. Rose Metal Industries serves clients across Tamil Nadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry), and Andaman & Nicobar Islands, providing reliable supply and custom solutions for industrial and offshore requirements..
F55 super duplex hexagon rods possess a unique combination of austenitic and ferritic microstructure, offering superior mechanical performance compared to conventional austenitic stainless steels. This balance ensures excellent toughness, high yield strength, and fatigue resistance, making them suitable for structural, marine, and chemical applications..
Chemically, UNS S32760 (F55) contains 24–26% Chromium, 7–9% Nickel, 3–5% Molybdenum, 0.2–0.3% Nitrogen, and low carbon (<0.03%). The high chromium, molybdenum, and nitrogen content provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, even in chloride-rich environments such as coastal or offshore conditions..
Rose Metal Industries supplies F55 hexagon rods in various sizes and custom lengths, with optional surface finishes including hot-rolled, pickled, and polished. The rods conform to international standards such as ASTM A276, ASTM A479, EN 10088, and UNS S32760, ensuring high-quality, traceable material. Mill Test Certificates (MTC) and third-party inspection reports are available to provide complete assurance of material compliance.
