ASTM A36M Steel
ASTM A36M steel is a carbon structural steel plate standard under ASTM (American Society for Testing and Materials) specifications. It is widely used in construction, industrial equipment, and structural applications due to its excellent weldability, moderate strength, and cost efficiency. ASTM A36M is the metric version of ASTM A36, specifying similar mechanical and chemical properties but in metric units.
ASTM A36M steel plate is considered a general-purpose structural steel, suitable for applications such as bridges, building structures, machinery platforms, and general fabrication where moderate strength and good formability are required.

Mechanical Properties of ASTM A36M Steel
| ASTM A36M Requirement | |
|---|---|
| >= 250 MPa | |
| 400–550 MPa | |
| >= 20% |
These properties make ASTM A36M suitable for moderate-load structural applications, combining reliability and ease of fabrication.
| <= 20 | >= 250 | 400–550 |
| 20–40 | >= 245 | 400–550 |
| >40 | >= 235 | 400–550 |
| 0.25 | |
| 1.20 | |
| 0.040 | |
| 0.050 | |
| 0.40 |
The controlled carbon and manganese content ensures excellent weldability and ductility.
