Ismail Flanges, based in Jakarta, Indonesia, has built a solid reputation as a reliable manufacturer and supplier of AISI 4130 flanges. These flanges are crafted from high-strength, low-alloy steel, specifically designed to handle high-pressure and high-temperature situations. AISI 4130, a chromium-molybdenum steel, is celebrated for its impressive strength-to-weight ratio, excellent weldability, and toughness, making it a go-to choice for critical applications in the oil & gas, petrochemical, and aerospace industries. Ismail Flanges offers a comprehensive selection of 4130 flanges, including weld neck, blind, socket weld, and threaded types, all produced to meet international standards like API, ASME, and ANSI, while also adhering to NACE requirements when necessary.
AISI 4130 flanges are crafted from a low-alloy steel that contains around 0.3% carbon, 0.8–1.1% chromium, and 0.15–0.25% molybdenum, which boosts their strength, hardness, and wear resistance. After undergoing heat treatment—typically through quenching and tempering—these flanges can reach a yield strength exceeding 415 MPa and a tensile strength of up to 655 MPa, all while maintaining good ductility and impact resistance. This alloy remains mechanically stable even under high temperatures and pressures, making it perfect for pressure-rated systems. Its outstanding weldability and machinability further enhance its popularity in critical industrial piping applications.
