The ASTM A193 Grade B7 Bolts is intended for higher temperature applications. Grade B7 bolts are tempered at a higher temperature, 1100° F minimum. This is why even if products seem interchangeable, they may not be. There could be a certain application that could produce circumstances that require specific Grades or ASTM standards to be maintained, and if a lesser or greater grade is used, a problem could develop.
