ASTM A354 Grades – Understanding Grade BC and Grade BD
The ASTM A354 specification is divided into two grades, each offering distinct properties for various applications:
- Grade BC: Provides moderate tensile strength and is often used in situations where both strength and toughness are required but extreme hardness is not critical. Grade BC is commonly used in automotive and structural applications where moderate strength and flexibility are essential.
- Grade BD: Known for high tensile and yield strength, Grade BD is the go-to for demanding environments with significant load requirements. Grade BD bolts are heat-treated to optimize their mechanical properties, making them suitable for highly stressed parts in construction and infrastructure.
