SA516GR.70 pressure vessel steel details in regard of performing ASME standard

SA516GR.70 steel is a ordinary material in pressure vessel steel. SA516GR.70 steel executive standard: ASTM and ASME .
SA516GR.70 specialty: Tensile Strength ＞485Mpa. The main element are including C,Mn,Si. Both P and S content decides its property. Other micro-element is rare.
In general, SA516GR.60N,SA516GR.70N (thickness ≤40mm ) steel plates can offer in rolling steel,normalizing or stress relief. Besides, it also can provide both normalizing and stress relief. Delivery condition of SA516GR.60N and SA516GR.70N (thickness ＞40mm ) steel plates is normalizing (unless the buyer specified). SA516GR.60N,SA516GR.70N (thickness ≤40mm ) steel plates ,when required notch toughness,should be normalized. If the buyer approved that the steel plates can allow to improve toughness with greater cooling rate compared to the air,the steel plates should be normalized under 1100-1300°F (595-705℃).
SA516GR.70 widely used in oil,chemical industry,power station and boiler field. Besides,SA516GR.70 is also used for making such equipment and component as reactor, heat ex-changer, separator,sphere, oil and gas tank, liquefied storage tank,boiler drum, liquefied oil and gas cylinders, hydro-power station with high pressure water pipe and turbine volute.
Other performing ASME standard: SA515Gr60、SA515Gr70、SA516Gr60、SA516Gr70、SA516Gr60N、SA516Gr70N.
