Brian Fasteners is a reputable Houston, USA-based supplier of Alloy Steel F2 Bars and Rods, providing high-quality materials that conform to ASTM A182 specifications. F2 is an alloy chromium-molybdenum steel for moderate temperature and pressure applications. Our rods and bars are recognized by their superior strength, toughness, and oxidation resistance. These characteristics make Alloy Steel F2 suitable for power generation, chemical processing, and industrial valve usage. At Brian Fasteners, we supply precision-machined F2 rod with consistent quality, rapid delivery, and full traceability for high-performance mechanical and structural applications.
Alloy Steel F2 has a composition of around 0.10–0.20% carbon, 0.40–0.65% manganese, 0.50–1.00% chromium, and 0.44–0.65% molybdenum. It has a tensile strength of 415–585 MPa and yield strength of approximately 205 MPa, with excellent ductility and elongation of 20–30%. F2 has moderate oxidation and thermal fatigue resistance, performing up to ~500°C. The alloy exhibits strength under cyclic stresses and is machinable with ease when in the annealed form. It compromises mechanical integrity and heat resistance, positioning it as a handy low-alloy product for high-demand engineering components.

They are used in high-temperature applications like pressure vessels, heat exchangers, and boilers, primarily in power generation and aerospace industries.
The combination of Chromium, Molybdenum, and Carbon enhances its resistance to oxidation and high-temperature degradation.
F2 steel alloy rods and bars find extensive applications in valves, flanges, fittings, and other pressure-containing components in steam and water systems. Their high performance under medium-temperature applications makes them find applications in power plants, refineries, and chemical plants. F2‘s resistance to oxidation and structural stability also find it applied in heat exchanger and boiler parts. This grade is preferred for repeated thermal cycling exposure and moderate pressure, providing sustained performance and ease of fabrication. The combination of strength, corrosion resistance, and cost-effectiveness of F2 steel renders it a good choice for pressure vessel and piping components.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
