Faizan Flanges is a trusted manufacturer and supplier of AISI 4130 Flanges in Doha, Qatar, delivering high-quality alloy steel products to meet demanding industrial requirements. AISI 4130 is a chromium-molybdenum alloy steel known for its excellent strength, toughness, and weldability. Our flanges are manufactured using advanced forging techniques and strict quality control measures to ensure dimensional accuracy, durability, and long service life. Faizan Flanges supplies AISI 4130 flanges in various sizes, pressure ratings, and standards to serve critical applications in oil & gas, power generation, and heavy engineering industries.
AISI 4130 Flanges are made from a chromium-molybdenum alloy steel, containing approximately 0.30% carbon, 0.80-1.10% chromium, and 0.15-0.25% molybdenum. This composition provides excellent strength, toughness, and weldability. Mechanically, AISI 4130 flanges offer a tensile strength of around 560 MPa and yield strength of 460 MPa, making them ideal for high-stress applications. The advantages include high resistance to corrosion, wear, and fatigue, along with the ability to perform well in harsh environments. These flanges are widely used in aerospace, automotive, and industrial sectors for critical, high-performance applications.
