A283
- This specification of ASTM A283 steel plate covers four grades (A, B, C, and D) of carbon steel plates of structural quality for general application.
- When the steel is to be welded, a welding procedure suitable for the grade of steel and intended use or service is to be utilized. See Appendix X3 of Specification A 6/A 6M for information on weldability.
- The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exactly equivalents; therefore, each system is to be used independently of the other, without combining values in any way.
- For plate produced from coil and furnished without heat treatment or with stress relieving only, the additional requirements, including additional testing requirements and the reporting of additional test results, of Specification A 6/A 6M apply.

Features of ASTM A283 Steel Plates:
| Principal Design Features | This ASTM specification covers low and intermediate strength carbon steel plates. |
| Applications | Used for general purpose structural applications of medium strength (60ksi tensile) requirement. |
| Machinability | Machinability of the steel covered by this specification is good, as for any low carbon steel. |
| Forming | Formability is good by conventional means, much the same as for 1030 plain carbon steel. |
| Welding | The steel covered by this specification may be welded by conventional methods. |
| Heat Treatment | Heat treatment consists of normalizing at 1650 F and slow furnace cool. |
| Forging | This specification is for plate product form and does not include forging. |
| Hot Working | Hot working of the plate steel may be done at 1650 - 1700 F or lower temperatures. |
| Cold Working | The steel is readily cold worked by conventional methods. |
| Annealing | Anneal at 1550 to 1800 F and slow furnace cool. |
| Aging | Not applicable. |
| Tempering | Not applicable in ASTM A283. |
| Hardening | Not applicable. |
| Other Comments | Properties of the steel covered by this specification are similar to AISI 1330 steel. See ASTM A283 for mechanical property requirements |
