SA516 Gr70 steel plate mechanical properties and application scope

SA516 Gr70 belongs to American standard steel plate for medium and low temperature pressure vessels, which is widely used in petroleum, chemical industry, power plant, boiler and other industries. SA516 Gr70 steel has low hardness, large thickness, high uniformity and other characteristics. Previously, the thickness of SA516 Gr70 steel plate used in China was mainly less than 150 mm, and the quality flaw detection performance was required to be national standard first level flaw detection. The materials under the same standard with SA516 Gr70 steel plate include SA516 Gr55, SA516 Gr60, SA516 Gr60N, SA516 Gr65, SA516 Gr70N.
