Mechanical properties of steel
Material standard for structural steel usually follow American Society for Testing and Materials ( ASTM ) standards.
- The ASTM specification A6 generally requirement of structural steel.
- The ASTM specification A370 provides steel testing procedures.
- The ASTM A36 is called mild steel (low carbon steel).
