Why choose this grade
ASME SA516 Grade 70 (Grade 70) is widely specified for pressure-vessel plates where a balance of strength, toughness and weldability is required. The normalized condition (N) provides improved Charpy impact properties for safe operation at reduced temperatures while maintaining the mechanical properties needed for pressure applications.
