You can ask mill to provide the analysis of the Boron (in certificate) and results shall show "Traces" and also the statement shall be there in certificate or through some letter from mill that "Boron is not added intensionaly"
Based on the two things mentioned above you can assure that the exessive boron does not present in your plates and you can convince your client.

Dear All
As per the SA 516 GR 70, boron content is not specified and shall not be present as specified element. For SA 516 GR 70 plate manufacturer certifies that this element is within permissible limit
Kindly give your suggestions to what basis we can certify for Coded vessels being constructed
Also kindly brief as to why the presence of boron and its affect??
Thanks in advance & regards
