Carbon Steel Piping Materials & ASTM Grades

Carbon steel is the fundamental material for industrial process piping due to its high tensile strength and versatility. Its performance depends heavily on the deoxidization manufacturing process—specifically, using fully “killed” steel to prevent porosity—and selecting the correct ASTM grade. While ASTM A106 (seamless) is mandated for high-temperature, high-pressure environments, ASTM A53 (welded or seamless) is … Read more
