Mechanical Properties

​A36 Steel Plate structural carbon steel​ exhibits the following characteristics:

1. ​​Excellent Weldability​​
   SA-36 structural carbon steel offers superior weldability, making it compatible with common welding processes such as arc welding and gas-shielded welding. This facilitates easy processing and connection in structural engineering applications.
2. ​​Outstanding Mechanical Properties​​
   SA-36 structural carbon steel delivers moderate strength and toughness, suitable for typical structural uses. It generally provides robust tensile strength​​ (400–550 MPa) and yield strength​​ (≥250 MPa), enabling it to withstand substantial loads and stress.
3. ​​Low Carbon Content​​
   The carbon content in SA-36 structural carbon steel is as low as 0.25%​​ (typically 0.25%–0.35%), ensuring excellent plasticity and workability. This allows it to be easily formed and machined into components of various shapes and sizes.
4. ​​Broad Applications​​
   SA-36 structural carbon steel is ​​widely used​​ in structural engineering projects, including:
   • Construction (e.g., building frames, beams, columns);
   • Bridges and infrastructure;
   • Shipbuilding (e.g., hulls, decks);
   • Pipelines and pressure vessels.
5. ​​Reliability and Cost-Effectiveness​​
   SA-36 structural carbon steel combines reliable performance with economic advantages. Its stable properties and relatively low cost make it a preferred choice for meeting the requirements of most structural engineering projects.
