The ASTM A182 F316/F316L forged socket weld cross is a fitting designed to connect four pipes at a central point, allowing for the distribution or collection of fluid flow in a piping system. Constructed from F316/F316L stainless steel, it provides excellent corrosion resistance, particularly in environments with high chloride concentrations, due to its composition of 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, with the low carbon content in F316L enhancing its resistance to intergranular corrosion. The socket weld design ensures a secure, leak-proof connection by allowing pipes to be inserted into the cross and then welded into place. This fitting is ideal for high-pressure and high-temperature applications, featuring mechanical properties such as a minimum tensile strength of 515 MPa and a yield strength of 205 MPa. Commonly used in industries such as chemical processing, petrochemical, and marine, it ensures reliable and durable performance.
