🟧 Product Overview
ASTM A516 is the most widely used pressure vessel steel grade in the world. It provides excellent notch toughness, weldability, and uniform mechanical properties, making it ideal for boilers, pressure vessels, heat exchangers, and industrial pressure systems.
A516 is available in Grades 55, 60, 65, and 70, with Grade 70 being the most commonly used due to its higher strength and toughness.
