Frequently asked questions about P235GH
What is P235GH used for?
P235GH is the unalloyed creep-resistant standard steel for piping and pressure vessels carrying water, steam and heating up to approx. 400 °C.
What does the GH in P235GH mean?
P stands for pressure loading, 235 for the minimum yield strength in MPa, G for the steel category and H for elevated temperature (creep-resistant).
What is the ASME equivalent of P235GH?
P235GH roughly corresponds to ASTM A106 Gr. A/B (tube) and A516 (plate).
