At Luke Steel, we take pride in offering top-notch Alloy Steel F5 Flanges, crafted specifically for industrial settings that demand resilience against high temperatures and corrosion. These flanges, made from a robust chromium-vanadium steel alloy, are perfect for environments where mechanical strength and resistance to thermal fatigue are crucial. You’ll find F5 flanges commonly used in sectors like power generation, petrochemicals, and chemical processing, where reliable and durable connections are a must, especially under high temperatures and pressures. Our F5 flanges adhere to strict industry standards for performance and quality, guaranteeing long-lasting reliability and safety in even the toughest applications.
Alloy Steel F5 Flanges are composed of 0.5% carbon, 5% chromium, and 1% vanadium, which together provide exceptional strength and resistance to thermal fatigue. These flanges boast a tensile strength ranging from 690 to 790 MPa, a yield strength of 480 MPa, and an elongation of 20 to 25%. They can handle service temperatures up to 570°C while keeping their structural integrity intact and resisting oxidation. The addition of vanadium enhances creep strength and stability at high temperatures, making F5 flanges perfect for critical applications in high-pressure systems that experience varying thermal conditions.
