SA516Gr70 application
SA516Gr70 widely used in petroleum, chemical, power plants, boilers and other industries for the production of the reactor, heat exchangers, separators, tank, gas tank, gas tank, the nuclear reactor pressure vessel, boiler, liquefied petroleum gas cylinders , Hydropower high-pressure water pipes, water wheels, vortex shell and other equipment and components.

SA516Gr70 the development
SA516Gr70 Wugang 2006 six new products, the steel plate in line with the NACE-MR0175 oilfield equipment sulfide stress cracking of metallic materials technical requirements, test and HIC + SSC. The steel plate for domestic initiative, the international leader. A516Gr70N meet the requirements of (ASME) ASTMA516/A516M standard and complete seek the needs of the oil to meet the high levels of sulfur and hydrogen gas, to reduce sulfur and hydrogen corrosion, reduce equipment maintenance, and increase the useful life of equipment. To characteristics of the steel plate: good resistance to impact, a small temperature deformation, welding performance and good performance of anti-fatigue, anti-layered sprinkle crack performance, micro-alloyed, high purity, low carbon equivalent resistance to sulfur hydrogen and strong product with good dimensional tolerances and surface quality, Henan PETROFER Iron & Steel Co., Ltd. is currently available for the steel plate thickness of 200mm below the The general requirements SAGr70 multi few of SA516Gr60, because its performance is more common, the domestic SA516Gr70 has been widely used in the major chemical sites.

Mechanical properties and chemical elements
SA516Gr70 tensile strength of 70 one thousand pounds / square inch, that is usually referred to is greater than 482. The main elements of the content of C Mn Si, p, s control to determine its performance. Other trace elements in very little. Materials and Testing Association standard, low temperature pressure vessels of carbon steel plate standard specification
Executive Standard: ASTM, ASME standards:
This standard is mainly used to improve the notch toughness of the welding pressure vessel steel plates.

Heat treatment
1.A516Gr55, A516Gr60 A516Gr65, A516Gr70 thickness of ≤ 1.5in The (40 mm) steel plate usually rolling state supplier, steel plate can also be normalized or eliminate stress, normalizing plus eliminate the stress order.
(2) the thickness of> 1.5in. (40mm) steel plate should be normalized.
(3) unless the demand side, otherwise the provisions of thickness ≤ 1.5in The (40mm) plate, the notch toughness requirements, should be normalized. If approved by the demand side, allowing greater than the cooling rate in order to improve the toughness in the air, but as long as the steel plate followed by tempering in the range of 1100-1300 ° F (595-705 ° C).
