Hudson Flanges, located in Midland, UK, is a trusted manufacturer and supplier of high-quality flanges for various industrial applications. We specialize in AISI 4140 Flanges, known for their exceptional strength, toughness, and wear resistance. AISI 4140 flanges are ideal for use in demanding industries such as automotive, aerospace, and oil & gas, where high performance and durability are essential. With a focus on precision and reliability, Hudson Flanges ensures that each product meets the highest standards of quality and performance.
AISI 4140 Flanges are made from a low-alloy steel containing approximately 0.40% carbon, 0.80-1.10% chromium, and 0.15-0.25% molybdenum. This composition offers excellent toughness, high tensile strength, and good fatigue resistance. Mechanically, AISI 4140 flanges have a tensile strength of 655 MPa and yield strength of 415 MPa. The advantages of AISI 4140 flanges include superior wear resistance, high strength, and good hardenability, making them ideal for high-stress applications. These flanges are widely used in automotive, aerospace, and oil & gas industries for reliable, long-lasting connections in harsh environments.
