Macroetch testing is a method for examining and rating transverse sections of bars and billets to describe certain conditions of macro segregation that are often characteristic of consumable electrode remelted materials. ASTM A604 covers testing and inspection and is applicable to bars, billets, and blooms of carbon, alloy, and stainless steel which have been consumable electrode remelted.
