Dear Stuar,
There is a specific photographs which are showing the rating of Macroetch Billets.
You have to purchase it from the ASTM Office.
And the rating is as 1,2,3,4,5. The best one is S1 and the Worst is S5. If you certify that your material is with S5 rating, sorry to say.. your material will never get the customer.
