SA516Gr70 steel plate is a kind of low alloy high strength steel plate with excellent mechanical properties and corrosion resistance. The steel plate is mainly used in the manufacture of high-pressure vessels, boilers, petrochemical and other fields.
The chemical composition of SA516Gr70 steel plate is one of the key factors to determine its performance. The chemical composition of the 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, Mn and other elements have an important impact on the strength and toughness of the steel plate, Si, P, S and other elements of the content of the corrosion resistance of the steel plate has a greater impact.
The mechanical properties of SA516Gr70 steel plate mainly include strength, plasticity and toughness. The steel plate has high strength and good toughness, its tensile strength and yield strength of 186 ksi and 152 ksi, respectively.In addition, SA516Gr70 steel plate also has good plasticity, its elongation and shrinkage of 36% and 60%, respectively. These excellent mechanical properties make this steel plate widely used in high pressure vessel, boiler, petrochemical and other fields.
The corrosion resistance of SA516Gr70 steel plate is mainly determined by its chemical composition and surface treatment process. The steel plate adopts appropriate chemical composition and alloying elements to make it have good corrosion resistance. In addition, SA516Gr70 steel plate has been subjected to appropriate surface treatment, such as shot peening and galvanizing, which further improves its corrosion resistance.
