Frequently Asked Questions

What is the chemical composition of ASTM A516 Gr. 70 Plate?+
A516 Grade 70 plate contains carbon 0.27% max, manganese 0.85-1.20%, silicon 0.15-0.40%, phosphorus 0.035% max, and sulphur 0.035% max per ASTM A516/ASME SA-516. Carbon limits increase with plate thickness.
What are the available thickness ranges for ASTM A516 Gr. 70 Plate?+
ASTM A516 Grade 70 plate is available from 6 mm (1/4") to 200 mm (8") or heavier. Plates under 40 mm (1.5") may be supplied as-rolled; plates 40 mm and above are normalised.
What is the difference between ASTM A516 Gr. 70 and Gr. 60 Plate?+
Grade 70 has higher tensile strength (70-90 ksi vs 60-80 ksi) and yield strength (38 ksi vs 32 ksi). Grade 70 is preferred for higher-pressure service. Grade 60 has better formability for moderate-pressure vessels.
What is the maximum operating temperature for ASTM A516 Gr. 70 Plate?+
A516 Grade 70 plate covers service down to approximately -20 °F (-29 °C) with impact testing per supplementary requirement S1. The upper service limit typically does not exceed 800 °F (427 °C).
What is the European equivalent of ASTM A516 Grade 70 Plate?+
The approximate European equivalent is EN 10028-2 P355GH (W.Nr. 1.0473). The specifications are similar in application and mechanical properties, but not identical. Direct substitution requires engineering review.
Is ASTM A516 Gr. 70 Plate weldable?+
ASTM A516 Grade 70 plate has good weldability due to its controlled carbon content. Common welding processes include SMAW, GMAW, GTAW, and SAW. Preheat and post-weld heat treatment (PWHT) requirements depend on plate thickness per ASME Section VIII. Thicker plates need preheat in the range of 200-400 degrees F to reduce hydrogen cracking risk.
