So, you called a machinist who has determined that the brinell hardness reading is greater on later blocks? 😂
Do you know how silly that sounds? All you want to do is argue. PM me if you really have questions.
Quantitative hardness testing on a representative sample of blocks cast on specific dates would be the only way to draw conclusions. I lived this Phil - please don’t just be contrary. PM me if you have questions.
