Gugsa Flanges, a reputable manufacturer and supplier located in Addis Ababa, Ethiopia, specializes in high-quality AISI 4140 Flanges that are built to handle the tough demands of various industrial applications. Renowned for their remarkable strength, durability, and precision engineering, these flanges are made from top-notch alloy steel, ensuring they can be relied upon even under high pressure and temperature conditions. Gugsa Flanges adheres to strict quality standards and employs advanced production techniques to provide products that perform efficiently across a range of industries, including oil and gas, petrochemical, power generation, and heavy machinery, guaranteeing a long service life and consistent performance.
AISI 4140 Flanges are primarily made up of chromium (0.8–1.1%), molybdenum (0.15–0.25%), carbon (0.38–0.43%), manganese (0.75–1.0%), and silicon (0.15–0.30%). This specific blend offers a well-rounded mix of strength, toughness, and resistance to wear and fatigue. Mechanically, these flanges boast high tensile strength (up to 1080 MPa), excellent yield strength, and outstanding hardenability. They maintain good ductility and impact resistance, even at elevated temperatures, making them perfect for heat-treated and stress-relieved industrial settings.
