sorry it took me so long to get back at you. We cut few pieces in half and checked them with a microscope. Please take a look at photos in attachment. It is pretty clear those „holes“ are not according to the drawing. There is no need to look up porosity standards in my opinion.As for those other components, we will scrap them on our charge, as a goodwill.Also did you find this defect when checking your stock? We wouldn’t like this to happen again.Please send us the credit note so we can scrap those NOK parts. I expect your reply, wednesday 14.7.2021 at latest.
