Characteristics of A516 Gr.70 steel plate

A516 Gr.70 steel plate meets the technical requirements of sulfide stress cracking resistant metal materials for NACE-MR0175 oilfield equipment and has passed HIC+SSC test. A516 Gr.70 steel plate meets the requirements of ASTMA516/A516M standard.

A516 Gr.70 steel plate also meets the needs of oil and gas with high content of sulfur and hydrogen, reduce the corrosion of sulfur and hydrogen, reduce equipment maintenance, increase the service life of equipment.

A516 Gr.70 steel plate has the following characteristics: good impact resistance, low temperature deformation, good weldability, good fatigue resistance, good anti-laminar spallation performance, micro-alloying, high purity, low carbon equivalent resistance to sulfur and hydrogen, good dimensional tolerance and surface quality. The currently available thickness for A516 Gr.70 steel plate is less than 200 mm. In China, A516 Gr.70 steel plate is usually used more than A516 Gr.60 steel plate, because A516 Gr.60 performance is more common. A516 Gr.70 steel plate is now widely used in major chemical sites.
