ASTM A178 Steel Tube is a standard specification for electric resistance welded carbon steel and carbon manganese steel boiler and superheater tubes.
ASTM A178 A boiler tube includes carbon, manganese, phosphorus and sulfur content. The carbon content is usually between 0.06% and 0.18%, and the manganese content is between 0.27% and 0.63%.
ASTM A178 A seamless boiler tube has a diameter of 1/2 inch to 5 inches and a wall thickness of 0.035 inches to 0.360 inches. ASTM A178 A carbon steel boiler tube is mainly used for boilers, boiler flues, superheater flues and safety ends.
