The ASTM A182 E347/F347H forged socket weld cross is a versatile pipe fitting designed to create a four-way connection in a piping system. Made from E347/F347H stainless steel, this cross is engineered for high-performance in environments where resistance to intergranular corrosion is critical. The addition of columbium (niobium) stabilizes the steel, preventing carbide precipitation and enhancing its suitability for high-temperature applications. The socket weld design ensures a strong, leak-proof joint, making it ideal for high-pressure systems. The forged construction of the cross provides exceptional durability and strength, which is essential for applications in industries such as petrochemical, chemical processing, and aerospace. Its robust design ensures reliable performance and long service life under demanding conditions.
