A516GR70 steel for pressure vessel

As a kind of pressure vessel, the technical requirement of oil storage tank is higher than that of steel plate for pressure vessel. With the development of petroleum chemical industry, power plant and other industries, large-scale, high pressure vessel number of the trend has become increasingly evident, demand a substantial increase in the amount of pressure vessel use conditions and the environment have become increasingly demanding, corresponding to pressure vessel plate technology requirements are also constantly improving. A516GR70 steel plate for medium and low temperature pressure vessel, which is provided by Henan Di Di metal material Co., Ltd, is widely used in pressure vessel industry at home and abroad.
　　Development of steel plate A516GR70 for medium and low temperature pressure vessel

　　A516Gr70N is one of the six new products developed in Wugang in the year of 2008. The steel plate is in line with the technical requirements of the anti cracking stress cracking metal material used in NACE-MR0175 oil field equipment, and is tested by HIC+SSC test. The plate for the domestic initiative, the international leader. A516Gr70N meets the requirements of (ASME) ASTM516/A516M standard, and meet the needs of high content of sulfur and hydrogen oil gas, reduce sulfur and hydrogen corrosion, reduce equipment maintenance, increase the service life of equipment. The plate has the characteristics: good shock resistance and small deformation temperature and good welding performance and anti fatigue performance and anti cracking performance of layered microalloyed high purity low carbon equivalent anti sulfur hydrogen ability of products with good surface quality and dimensional tolerances are currently available for steel plate thickness below 200mm.
