Introductions about ASTM A573 Gr 70 steel plate

What is ASTM A573 Gr 70 steel plate?

ASTM A573 Gr 70 steel plate is structural quality carbon manganese silicon steel. ASTM A573 Gr 70 steel plate is intended primarily for structural applications at atmospheric temperatures for which improved toughness is required. For ASTM A573 Gr 70 steel plate, BBN steel can arrange shot blasting and painting in our processing plant for clients if the end customers need the treatment. BBN steel would also issue the original mill test certificate EN 10204 3.1 for clients when arrange delivery, so that clients can trace the ASTM A573 Gr 70 steel plate origin easily.
