The ASTM A182 F304 forged socket weld half coupling is a vital component used to connect a pipe to a fitting or another pipe section. Made from F304 stainless steel, it provides excellent corrosion resistance and strength due to its composition of 18-20% chromium and 8-10.5% nickel. This half coupling is designed for high-pressure and high-temperature applications, offering a minimum tensile strength of 515 MPa and yield strength of 205 MPa. Typically available in sizes ranging from 1/2″ to 4″ and pressure ratings such as Class 3000 and Class 6000, it ensures a secure and durable connection in various industries including oil and gas, chemical processing, and power generation. The forged and heat-treated construction ensures reliability and long service life in demanding environments.
