What is the domestic standard equivalent to the SA516 standard?
Thread Content
I have a question: What is the domestic standard corresponding to SA516? What are the corresponding domestic standards for SA516Gr55, Gr60, Gr65, and Gr70? Thank you!
If the poster wants a precise comparison, they can use SA516 and national standards to compare the chemical compositions. It is generally believed that SA516 is the closest to Q345R.

Q345R is a material specified in GB713; there is no overlap between GB713 and SA516 standards. The 4 steel grades listed in SA516 also share no similarities with the materials in GB713, let alone be interchangeable with them. There are many discussions on this topic in our forum; I suggest the original poster use the forum’s search function to find them. Or read the standards. Wugang Panglong
