Luke Steel is a well-known manufacturer and supplier located in Houston, USA, specializing in top-notch Alloy Steel Flanges for demanding industrial applications. We’ve built a reputation for precision engineering and unwavering quality, ensuring our flanges meet global standards like ASTM, ASME, and ANSI. Our alloy steel flanges are crafted to perform exceptionally well under high pressure, extreme temperatures, and corrosive environments. At Luke Steel, we employ cutting-edge manufacturing techniques and rigorous quality control to guarantee that our products offer reliable sealing, structural integrity, and long-lasting durability. We proudly serve industries such as oil & gas, power generation, petrochemical, and marine, providing flange solutions tailored to critical operations.
Alloy Steel Flanges are made using a mix of alloying elements like chromium, molybdenum, nickel, and vanadium, which boost their strength, toughness, and resistance to corrosion and high temperatures. Common grades like ASTM A182 F5, F9, F11, and F22 can achieve tensile strength up to 860 MPa and yield strength between 415–620 MPa. These flanges undergo heat treatment to enhance their mechanical properties, ensuring they perform excellently in extreme service conditions. Their unique composition provides outstanding wear resistance, pressure containment, and a long service life, making them perfect for high-stress and high-temperature pipeline and vessel connections.
