Notes:
1. When yield is not significant, Rp0.2 may be used.
2. For thickness >60 mm, elongation may be reduced by 1%.
3. Impact test uses longitudinal specimens.
4. Impact temperature by grade: B 20°C, C 0°C, D -20°C, E -40°C, F -50°C. (Grade E offers -40°C impact, 47J min)
5. This grade exhibits enhanced yield strength: 550 MPa up to 40mm, 530 MPa for 40-100mm.
