SA516Gr70
SA516Gr70 belongs to the low temperature pressure vessels, with carbon steel, executive ASME specifications, effectiveness research and production in 2006, it is different from SA516Gr60 lies in tensile strength. Brand and: SA515Gr60, SA515Gr70, SA516Gr60, SA516Gr70 standards: the United States ASTM, ASME specifications:
SA516Gr70 applications
SA516Gr70 widely used in petroleum, chemical industry, power plant, boiler, etc, and used to make the reactor, heat exchanger, separator, spherical tank, gas cylinder, liquid tank, nuclear power reactors island, boiler drum, liquefied petroleum gas cylinders, high pressure water pipes, turbine hydropower station equipment and components such as spiral case.

SA516Gr70 effectiveness is 2006 annual development of one of the six new products, steel plates meet NACE-MR0175 oilfield equipment with resistance to sulfide stress cracking metal material requirements, and through the HIC + SSC test. The steel plate for the domestic initiative, international lead. A516Gr70N meet (ASME) ASTMA516 / A516M standard requirements, and the o meet high content of sulfur and hydrogen oil gas needs, reduce corrosion of sulfur and hydrogen, reducing equipment maintenance, increase the service life of equipment. The steel plate have the features: impact resistant performance is good, temperature deformation is small, the welding performance is good, anti-fatigue performance is good, the layer and crack performance is good, micro alloying, high grade, low carbon equivalent of sulfur hydrogen ability, the product has good dimensional tolerance and surface quality and now available for 200 mm of thickness of the steel plate. General requirement with the domestic SAGr70, SA516Gr60 few because its performance are normal, domestic SA516Gr70, now has been widely used in various chemical field.
