Hello everyone, I purchased a batch of A105 butt-welded flanges. During the material testing, it was found that the silicon content was above the specified limit, ranging from 0.495 to 0.503. Will this affect their usability? What are the risks if it is used?

What is the Mn content? Could it be 16Mn?

This is the material that was detected. Can this material be welded using ordinary welding rods and No. 20 steel pipes?
