To make sure correctly material delivery, material ordering information shall be complied with specification.
Ordering information and general requirement
See requirement in Section 4 of ASTM A6/A6M-17a
| Ordering information | Example |
|---|---|
| ASTM product specification designation and year-date | ASTM A36-17a |
| Name of structural product | Plate |
| Shape designation | thickness 6 mm, width 1354 mm |
| Grade, class and type of designation | - |
| Condition delivery | as-rolled |
| Quality | 50 sheets |
| Length | 6096 mm |
| Supplementary requirement | See S5, S30, S32 in ASTM A36 |
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, …
We are recommeded to order material from Hyundai Steel, POSCO, Nippon Steel, TATA, and other global steel company. You will recieve the compliance of their data reports in the MTC and verification of specification requirement.
Material and manufacture
The steel shall be killed.
Chemical composition
Please check the chemical analysis in Table 3 of ASTM A36.
Note: product analysis tolerance in Table A of Specification A6.
- Heat analysis: test on casting, another name heat, casing.
- Product analysis: test on production after forming.
- % C and %Mn deviation see foot note B in Table 3 of ASTM A36.
Sampling for chemical analysis and methods of analysis shall be in accordance with ASTM A751.
Tension test
Tensile requirement in Table 2, you should refer to specification and compare with the MTC.
Remarks the foot note A) B) C) D) E) in Table 2 of ASTM A36 and then refer to ASTM A6 Para. 11 to check the statement in the MTC such orientation of test sample (transverse or longitudinal).
Test sample should verify in the MTC:
- Position of test sample: top, bottom or middle.
- Tensile test: direction, size and gauge length of sample.
Minimum number of tension test required, see Table B in ASTM A6.
Quality
See Para. 9 in ASTM A6: … structural products are normally furnished in the as-rolled condition and are subjected to visual inspection by the manufacturer or processor.
Refer to product form and delivery condition in the purchase order.
Permitted variations and dimensions and weight
See Para. 12 in ASTM A6.
Test reports
Test reports for each heat supplied are required, see Para. 14 in ASTM A6.
Identification of structural products (markings)
Plate markings
| Required product markings | Example |
|---|---|
| ASTM designation | ASTM A36/A36M (year-date not required) |
| Grade | (not required for A36) |
| Heat number | xxxxx |
| Size and thickness | 6 x 1254 x 6096 mm |
| Name, brand or trademark of manufacturer | logo or tradename (NSSMC) |

For structural products finished by other than the original manufacturer, the supplier of the structural product shall also provide the purchaser with a copy of the original manufacturer’s test report (Supplier shall certify true copy).
Location markings
At least one plate of each finished plate or production.
Other products and required marking, see Para. 18 of ASTM A6.
