We are facing issue of surface defects arising on peritectic grade plates (non micro alloyed) steel. What can be the reason for this kind of defect?

One of our plants make peritectic grade structural plates ( Carbon 0.15-0.17 %, Mn 0.8-1.1 %, Si - 0.2 - 0.3%, Al-0.03-0.04%). Recently we are noticing appearance of surface defects of the nature...
