Under standard ASTM SA516M, there are four grade of pressure vessel steel plates--Grade 55, Grade 60, Grade 65 and Grade 70. And the maximum thickness of ASTM SA516 plates is limited only by the capacity of the composition to meet the specified mechanical property requirements.
The steel ASME SA516 Grade 55 shall conform to the chemical requirements given in Table 1 unless otherwise modified in accordance with Supplementary Requirement S17, Vacuum Carbon-Deoxidized Steel in Specification A20/A20M. For S17 supplementary requirements as following: Material ASME SA516 Grade 55 shall be vacuum carbon-deoxidized, in which case the silicon content at the time of vacuum deoxidizing shall be 0.12% maximum, and the content of deoxidizers such as aluminum, zirconium, and titanium should be kept low enough to allow deoxidation by carbon. The test report shall indicate that the steel was vacuum carbon-deoxidized.
The minimum heat analysis and product analysis requirements for silicon do not apply to vacuum carbon-deoxidized steel.
