The ASTM A182 F304 forged socket weld full coupling is designed to join two pipes of the same diameter in a piping system. Made from F304 stainless steel, this coupling offers exceptional resistance to corrosion and high mechanical strength due to its composition of 18-20% chromium and 8-10.5% nickel. With mechanical properties including a minimum tensile strength of 515 MPa and yield strength of 205 MPa, it is suitable for high-pressure and high-temperature applications. Available in sizes ranging from 1/2″ to 4″ and pressure ratings such as Class 3000 and Class 6000, this coupling is widely used in industries such as oil and gas, chemical processing, and power generation. The forged and heat-treated construction ensures durability and reliable performance in demanding environments.
