We take pride in our precision engineering and reliable performance, ensuring that our AISI 4130 flanges can handle high-pressure and high-temperature conditions with ease. Thanks to our state-of-the-art manufacturing facilities and rigorous quality control, every flange we produce meets international standards. Our dedication to durability, prompt delivery, and customer-centric solutions has made Quan Flanges and Plates a trusted partner for essential applications in the oil, gas, petrochemical, and industrial sectors.
AISI 4130 flanges are primarily made from chromium (0.8–1.1%) and molybdenum (0.15–0.25%) alloyed with carbon steel, striking a perfect balance between strength, toughness, and hardenability. The chemical makeup also includes carbon (0.28–0.33%), manganese (0.4–0.6%), silicon (0.15–0.35%), along with trace amounts of sulfur and phosphorus. In terms of mechanical properties, AISI 4130 flanges boast a tensile strength of 560–670 MPa, a yield strength of around 460 MPa, and an elongation of 25%. They offer outstanding fatigue resistance, impact toughness, and weldability, making them perfect for high-pressure and high-stress applications.
