What is the A573/A573M carbon steel plate standard?
ASTM A573/A573M is a standard specification for carbon steel plates for structural purposes. It is mainly used for structural members that require good toughness and high strength, especially for welded structures in buildings and bridges.

ASTM A573/A573M carbon steel plates are mainly used in structural engineering such as buildings and bridges, especially for components that require high toughness and weldability. Grade 58 is suitable for structures that require higher toughness, Grade 65 balances strength and weldability, and Grade 70 is used for structures with higher load-bearing capacity, such as large bridge girders. These steel plates ensure structural safety and durability.
