EN P295GH has lower carbon (≤ 0.20%) for better ductility, while GB Q345R has higher manganese for added strength.
  • Mechanical Equivalence: Equivalents like EN P295GH and JIS SPV315 offer higher yield strengths (295-315 MPa) for thinner plates, making them suitable substitutes in designs where SA516 Gr 65’s 240 MPa yield is sufficient. BS 224-460A/B matches closely in tensile strength, with optional impact testing for low-temperature use.
  • Performance in Applications: All equivalents are used for pressure vessels, but SA516 Gr 65’s normalization ensures uniform properties, while equivalents like DIN 17Mn4 may require additional heat treatment. For sour gas, HIC-tested versions of SA516 Gr 65 and equivalents like EN P295GH are preferred.
