With a **minimum yield strength of 100 ksi (690 MPa)** for thicknesses up to 19 mm, Grade D distinguishes itself through a carefully balanced chemical composition that prioritizes enhanced **through-thickness strength and notch toughness**. This makes it particularly suitable for highly stressed, dynamically loaded components in demanding environments where failure is not an option. --- **Key International Standards** - **Primary Specification:** ASTM A514/A514M - *Standard Specification for High-Yield-Strength, Quenched and Tempered Alloy Steel Plate, Suitable for Welding* - **Dimensional Standards:** ASTM A6/A6M - *General Requirements for Rolled Structural Steel* - **International Equivalents:** - **EN Standard:** EN 10025-6 Grade S690QL1 (comparable strength and impact requirements) - **ISO Standard:** ISO 4950-3 Grade EQ 690 (equivalent quality level) - **JIS Standard:** JIS G3128 SHY685-F (similar high-toughness grade) -
