The ASTM A182 F304/F304L forged socket weld cross is a key fitting used to connect four sections of pipe at a single intersection, designed for strong, leak-proof joints. Made from F304 or F304L stainless steel, it offers exceptional corrosion resistance and durability due to its composition of 18-20% chromium and 8-10.5% nickel, with F304L providing a lower carbon content for enhanced weldability. This cross features high tensile strength (minimum 515 MPa) and yield strength (minimum 205 MPa), making it suitable for high-pressure and high-temperature applications. Available in various sizes and pressure ratings, this fitting is commonly used in industries such as oil and gas, petrochemical, and power generation. The cross is forged and heat-treated to ensure reliable performance and longevity in demanding environments.
