Well, i know it was one of 3 different grades. We have the print that specifies what rods the builder could of used and 5356 was one and i think 5056 was another. I'm waiting on the other exact 2 rods that could of been used. The repairs are minor just some overlap that needs to be ground out and some crater cracks that need to be ground and filled at the start and stops of these increment welds. I guess i will have to have these guys do some digging for the documentation on what was used.
