ASME SA516 Grade 60 / ASTM A516 Grade 60 Boiler Plate Steel

It is important to be aware of ASTM A20 or ASME SA20 (Specification for General Requirements for Steel Plates for Pressure Vessels). This specification outlines the testing and retesting methods and procedures, permissible variations in dimensions and mass, quality and repair of defects, marking, loading, and ordering information. It also contains a list of supplementary requirements which can be added to the basic A516 / SA516 specification when additional control, testing, or examination is required to meet end use requirements.
The supplementary requirements in A20 / SA20 are numbered (S1, S2, S3, and so on) and cover things like charpy v-notch impact tests (S5), product chemical analysis (S2), and simulated post weld heat treatment (S3).
As a matter of course, and in order to provide the best possible service to our customers, we stock ASTM A516 Gr. 60 and ASME SA516 Gr. 60 plates with numerous supplementary requirements included and all noted on the material test certificate supplied with each plate.

A516 / SA516 is a remarkably straightforward standard in its basic form with just five key chemical elements specified along with three mechanical properties that can be seen in the tables below this section.                                          More information – comparable specifications
On other websites, any suggestion that one steel specification and grade is an equivalent to another should be treated with caution especially because of differences in the methodology and techniques used for testing.

However, ASTM A516 Gr. 60 and ASME SA516 Gr. 60 are broadly similar to the following steel specifications:
