SA105
SA105 is a specification in the ASME (American Society of Mechanical Engineers) standards, specifically ASME B16.5, which covers materials and dimensions for pipe flanges and flanged fittings. SA105 refers to a particular grade of carbon steel forgings for piping applications.
Overall, SA105 carbon steel forgings are widely used in piping systems and other industrial applications due to their good combination of mechanical properties, weldability, and availability, making them suitable for a wide range of pressure and temperature conditions.
