In ER70S-3, the 70 indicates which property?

Explanation:
The number shown represents the weld metal’s strength rating. In this designation, 70 means the weld metal is specified to have a minimum tensile strength of about 70 ksi (thousand pounds per square inch). That tensile strength is a measure of how much pulling stress the welded joint can withstand before it would fail, which is a key factor in deciding if the filler metal is suitable for the load the joint will carry. This value is not about carbon content, weld position, or surface finish—the other aspects of the code describe other properties, not the strength class. So the 70 directly communicates the strength capability of the weld metal.
