Kabby Flanges is a reputable manufacturer and supplier of top-notch AISI 4130 Flanges based in Abuja, Nigeria. Crafted from AISI 4130 alloy steel, these flanges boast remarkable strength, toughness, and weldability, making them perfect for medium to high-pressure applications. Built to meet international standards like ASTM and ASME, our AISI 4130 flanges guarantee precise dimensions, reliability, and leak-proof performance. Available in various styles such as weld neck, slip-on, blind, and threaded, these flanges are extensively utilized in industries like oil & gas, petrochemical, power generation, and machinery, ensuring durable and efficient pipeline connections.
AISI 4130 Flanges are primarily composed of chromium (≈0.8–1.1%), molybdenum (≈0.15–0.25%), manganese (≈0.8–1.1%), carbon (≈0.28–0.33%), and silicon (≈0.15–0.35%), with iron making up the rest. This alloy delivers impressive tensile strength (≈560–760 MPa), yield strength (≈435–615 MPa), and good ductility (≈20% elongation). It also showcases high toughness, fatigue resistance, and moderate corrosion resistance, making it well-suited for challenging industrial environments. AISI 4130 steel can be heat-treated to boost hardness or strength as required while still maintaining excellent weldability for construction and pipeline projects.
