SA516 GR.70N Stationary Tubesheet For Power Plant Boilers , Heat Exchangers
GR.70N (Grade 70 Normalized) is a designation for carbon steel plates used in pressure vessels and boilers. It falls under the ASTM A516 specification, which covers steels intended for moderate- and lower-temperature service. The "N" indicates that the material has undergone a normalizing heat treatment process, enhancing its mechanical properties and making it more suitable for pressure-containing applications.
SA516 GR.70N Stationary Tubesheets leverage these properties to provide critical support and alignment for tubes in heat exchangers, boilers, and pressure vessels. These tubesheets are widely used in industries such as power generation, chemical processing, petrochemical refining, and oil and gas, ensuring efficient heat transfer and mechanical stability in high-pressure and corrosive environments.
