What is Carbon Steel A671 Gr CC 65 Pipe?

Carbon Steel A671 Gr CC 65 Pipes are manufactured from carbon steel plates with controlled chemical composition, including carbon, manganese, phosphorus, and sulfur. The CC 65 grade offers good tensile and yield strength, excellent toughness, and reliable resistance to internal pressure. Post-weld heat treatment enhances structural integrity and stress relief. These pipes exhibit good weldability, dimensional stability, and consistent mechanical performance, making them suitable for pressure and structural piping applications.
