What are ASTM A 178 Gr.A, Gr.C Welded Boiler Tubes?

ASTM A 178 is a specification that covers minimum wall thickness, electric-resistance-welded tubes made of carbon steel, and carbon-manganese steel with a minimum tensile strength of 60,000 psi. The tubes are available in two grades, Grade A and Grade C. The difference between these two grades lies in their chemical composition, specifically their carbon content. Grade A has a maximum carbon content of 0.27%, while Grade C has a maximum carbon content of 0.35%.

ASTM A 178 Gr.A, Gr.C Welded Boiler Tubes are commonly used in various industries, including power plants, oil refineries, and chemical plants. They are also used in heat exchangers, condensers, and other applications where high-pressure and high-temperature environments are present. This grade of tube has excellent mechanical properties, including high tensile strength, good toughness, and resistance to corrosion.
