Low Carbon A516 Grade 55 Pressure Steel

Low Carbon A516 Grade 55 Pressure Steel

ASTM A516 Grade 55 is a low-carbon steel plate specification for building pressure vessels and boilers used in moderate to low-temperature service, prized for its toughness, weldability, and strength in industries like oil & gas. It offers good performance for less demanding pressure applications, with its properties determined by its controlled carbon/manganese content and impact testing, making it ideal for storage tanks, heat exchangers, and large fabrications.
