What are the mechanical properties of SA516 carbon steel

The mechanical properties of SA516 carbon steel, which is part of the ASTM A516 specification for pressure vessel plates, can vary depending on the specific grade and heat treatment. However, here are some typical mechanical properties for SA516 carbon steel:

- Tensile Strength: The minimum tensile strength for SA516 ranges from 380 MPa (55,000 psi) to 620 MPa (90,000 psi), depending on the grade.
- Yield Strength: The minimum yield strength for SA516 varies between 205 MPa (30,000 psi) and 415 MPa (60,000 psi) for different grades.
- Elongation: The minimum elongation at break for SA516 typically ranges from 21% to 27%, depending on the grade.
- Impact Toughness: SA516 carbon steel exhibits good impact toughness characteristics required for pressure vessel applications.

It's important to note that these mechanical properties might change based on factors such as plate thickness, heat treatment, and specific grade within the SA516 range. For precise mechanical property values, it is advisable to refer to the material's mill certification or consult the manufacturer's specifications and relevant standards such as ASTM A516/A516M.
