Arda Flanges, based in Istanbul, Turkey, stands out as a top-notch manufacturer and supplier of high-quality Alloy Steel F91 Flanges. Renowned for their precision engineering and commitment to international quality standards, Arda Flanges produces flanges that boast remarkable strength, durability, and resistance to high-temperature oxidation and corrosion. These Alloy Steel F91 Flanges are specifically crafted for tough industrial applications, especially in the power generation and petrochemical sectors, where high pressure and temperature are the norm. With a strong emphasis on reliability, prompt delivery, and customer satisfaction, Arda Flanges guarantees that each flange adheres to strict specifications, providing industries with robust and long-lasting piping solutions.
The composition of Alloy Steel F91 Flanges primarily includes iron, along with alloying elements like chromium (8–9%), molybdenum (0.85–1.05%), vanadium (0.18–0.25%), and small amounts of niobium and nitrogen. This unique blend results in outstanding mechanical strength, high creep resistance, and impressive hardness. These flanges showcase a tensile strength ranging from 585 to 750 MPa, yield strength between 415 and 550 MPa, and hardness levels of 200 to 250 HB. The combination of toughness, ductility, and resistance to high-temperature oxidation makes Alloy Steel F91 Flanges ideal for critical high-pressure and high-temperature industrial applications.
