Alloy F55 Round Bars Manufacturer, Stockist and Exporter

Alloy F55 Round Bars, also known as UNS S32760, are super duplex stainless steel bars that combine high strength with excellent corrosion resistance. These bars are widely used in chemical, petrochemical, and offshore applications due to their outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. The alloy features a balanced duplex microstructure that gives it superior mechanical properties compared to standard austenitic stainless steels. It is ideal for environments containing chlorides, acids, and other aggressive chemicals. Fabrication processes such as welding, machining, and forming are possible with appropriate precautions. F55 round bars are available in various diameters and lengths to suit specific project requirements. Their combination of durability and corrosion resistance makes them highly reliable in extreme conditions.

The chemical composition of Alloy F55 Round Bars includes high amounts of chromium, molybdenum, and nitrogen. Chromium provides excellent resistance to oxidation and localized corrosion, while molybdenum enhances pitting resistance in chloride environments. Nitrogen strengthens the steel and improves resistance to stress corrosion cracking. Small amounts of nickel and iron balance the duplex microstructure and contribute to the alloy’s mechanical stability. Carbon content is kept low to minimize carbide precipitation and intergranular corrosion. Some bars may also contain traces of manganese, silicon, and copper to optimize processing and performance. This careful composition ensures that Alloy F55 performs reliably in high-stress and corrosive applications.

Mechanical properties of Alloy F55 Round Bars are exceptional, offering high tensile strength and yield strength compared to conventional stainless steels. Typical tensile strength ranges from 850 to 950 MPa, and the yield strength is approximately 550 to 650 MPa. These bars maintain good toughness even at low temperatures, making them suitable for cryogenic and marine environments. They exhibit moderate elongation, ensuring flexibility under heavy loading without cracking. Hardness typically ranges between 250–300 HBW, depending on heat treatment. These mechanical characteristics make F55 round bars suitable for high-pressure vessels, pumps, and shafts in aggressive environments. The alloy’s combination of strength and corrosion resistance reduces maintenance and replacement costs over time.

Alloy F55 Round Bars are commonly available in various standard dimensions, ranging from small diameters like 6 mm to large diameters exceeding 200 mm. Lengths are usually customizable depending on the supplier and project requirements. The bars can be supplied in hot-rolled, cold-rolled, or forged conditions to meet mechanical property specifications. Surface finishes include bright, pickled, or polished options depending on application needs. Weight charts are available to help calculate mass per unit length for precise engineering calculations. The bars are generally supplied in straight lengths, but they can be cut, machined, or fabricated as needed. This flexibility allows engineers to incorporate F55 seamlessly into different components and systems.

Applications of Alloy F55 Round Bars span multiple industries where corrosion resistance and strength are critical. They are widely used in oil and gas, chemical processing, pulp and paper, and desalination plants. In offshore environments, F55 resists chloride-induced pitting and stress corrosion cracking better than conventional stainless steels. The alloy is also used for manufacturing pumps, valves, heat exchangers, and marine fasteners. Its duplex structure ensures dimensional stability even under cyclic loads. Many engineers prefer F55 for high-pressure piping systems and pressure vessels. The combination of reliability and longevity reduces operational downtime and enhances overall plant safety.

Fabrication of Alloy F55 Round Bars requires specialized techniques due to the alloy’s high strength. Welding must follow duplex stainless steel procedures, including proper filler metals and pre/post-weld heat treatments. Machining is possible, but tools with high hardness and proper lubrication are recommended. Cold working increases strength but may reduce corrosion resistance if overdone. Annealing can restore ductility and relieve internal stresses after forming operations. These precautions ensure that the material retains its superior corrosion resistance and mechanical properties. Manufacturers provide detailed guidelines for processing to maintain the alloy’s performance in critical applications.

Alloy F55 Round Bars also have several equivalent grades in international standards, including UNS S32760, EN 1.4501, and ASTM A182 F55. They are often compared with other super duplex alloys like Alloy 2507, which has similar properties but slightly different chemical composition. Weight and dimension charts, as well as mechanical and chemical specifications, are widely available for precise engineering calculations. Maintenance requirements are minimal due to the alloy’s inherent corrosion resistance. Regular inspections and proper cleaning are sufficient to ensure long service life. Overall, F55 round bars are a premium choice for engineers requiring high-performance stainless steel components in aggressive environments.
