ASTM A576 is a specification for carbon steel bars intended for use in mechanical and structural applications, while Grade 8 refers specifically to a grade of high-strength bolts and fasteners made from alloy steel. Although both involve carbon and alloy steels, they are not directly equivalent, as they serve different purposes and have different mechanical properties. Therefore, ASTM A576 and Grade 8 are not interchangeable.
