ASTM A516/A516M-17 – Standard Speciﬁcation for Pressure Vessel Plates, Carbon Steel, for Moderate- and Lower-Temperature Service
To easy to review and learning, I add a MTC of plate ASTM A516 Gr. 70 EN 10204 Type 3.2.
NOTE: This is a MTC type 3.2, So you request the supplier to provide Surveyor Report for this MTC. You may have a concern on it, please read topic https://weldinginspections.net/t/845 .
(Please click to zoom out to view)
Under specification we have 4 grades, here we added P-Number and Group Number for references. Please check your WPS and range of qualifications.
MTC conform to inspection type 3.2 should be verified below information in MTC and Surveyor Report:
- Mill or manufacturer and address of factory
- Purchase name
- Order number
- Specification and grade
- Plate number and heat number
- Original markings and stamping
- Endorsed by Surveyor
|Grade||Tensile Strength (ksi)||P-Number||Group Number|

|60||60 – 80||1||1|
|65||65 – 85||1||1|
|70||70 – 90||1||2|
P-Number and Group Number as per ASME Section IX QW-422.
1. Ordering information and general requirement

Additional information should be included in material requisition such type of inspection document MTC 3.1 or 3.2, production test, max. carbon equivalent (CE), country of origin, approval vendor list, …
2. Material and manufacture
The steel shall be killed.
3. Heat treatment
- Plate, < 40 mm: as-rolled condition or normalized, or stress relieved.
- Plate, > 40 mm: normalized.
4. Chemical composition
Chemical requirements are given in Table 1 of ASTM A516.
- L = Heat analysis
- P = Product analysis
In addition to basic requirement to conform find austenitic grain size in Table 1 of ASTM A20.
Sampling for chemical analysis and methods of analysis shall be in accordance with ASTM A751.
5. Tension test
Tensile requirement in Table 2 of ASTM A516.
Please check back MTC attachment, you found the testing reports were given in the MTC (for plate 25x2438x9144, Product No. PB35407801-7802, Heat No. SB64008):
- Tension: PP14468005 (Position of test specimen is Transversal Direction)
- Impact: PP14468005
- Impact: PP14468008
6 Notch-toughness tests
Verify: number, size of specimens, absorbed valves, test temperature, orientation of test specimens
Surface imperfections and edge imperfection, repair by welding, see Section 9 of ASTM A20.
8. Permitted variations and dimensions and weight
See Para. 14 of ASTM A20.
9. Test report
The manufacturer or processor shall report:
- results of all tests required,
- purchase order,
- the heat number, the plate number,
- nominal thickness,
- the year-date of the specification,
- elongation values, both the percentage increase and the original gage length,
- all heat treatment,
- if CVN test are required, the test specimen size shall be reported,
- type of inspection documents,
