The ASTM A213 Stainless Steel 304 Tubes have higher temperature as well as pressure and therefore suitable stainless steel tubes that can be used in boilers, superheaters, and heat exchangers. In the meantime, ASTM A269 SS 304 Tubes are extremely fit in terms of general engineering and instrumentation uses, because they are stupendously weldable and formable. The standards guarantee that all tubes show a consistent thickness of the wall and dimensions and better performance in extreme working conditions.
