SA516GR70 Pressure Vessel Steel Plate Description
SA516GR70 Pressure Vessel Steel Plate is a low-alloy high-strength steel plate, which is one of the SA516 series steel plates. SA516 series steel plate is made of pressure vessel steel in American ASME standard, with excellent mechanical properties and corrosion resistance, widely used in petroleum, chemical, electric power, shipping, medicine and other fields of pressure vessels and other structural materials.
The chemical composition of SA516Gr70 steel plate mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), chromium (Cr), nickel (Ni), molybdenum (Mo) and other elements. Among them, the content of C, Si, Mn, P, S has an important impact on the mechanical properties and corrosion resistance of the steel plate.SA516Gr70N meets the requirements of ASME A516/A516M standards, and meets the needs of oil gases with high sulfur and hydrogen content, reducing sulfur and hydrogen corrosion, reducing equipment maintenance, and increasing the service life of equipment. The steel plate has the following characteristics: good impact resistance, small temperature deformation, good welding performance, good fatigue performance, good anti-layer cracking performance, micro-alloying, high purity, low carbon equivalent resistance to sulfur and hydrogen, the product has good dimensional tolerance and surface quality, currently available for thickness of 200mm or less steel plate.
