The ASTMÂ F304L 180-degree elbow is a fitting used to reverse the direction of flow in a piping system by 180 degrees. Made from F304L stainless steel, known for its low carbon content, this elbow offers excellent resistance to intergranular corrosion, especially after welding. It is suitable for high-corrosion environments such as chemical processing, food and beverage, and pharmaceutical industries. The 180-degree angle is particularly useful in compact piping layouts where a smooth return flow is required without changing the piping elevation or orientation.
