As per A515/A515M , Gr 70 mentioned the maximum allowable carbon content for plate over 2 inch is 0.35% , what is the minimum carbon content acceptable for this Grade , this is the first question ?
We have one plate with very very low carbon content around 0.049 % & other element content all with the range of 515 Gr 70 like Si=0.27 , Mn=1.42 , P=0.018 , S=0.005 & Fe=97.9 , plus the Tensile value around 510 N/mm2 .
Can we consider this plate comply with A515/A515M Gr 70 even the carbon content is very low ?
