What is the meaning of GH in P265GH?
P265GH is explicitly classified as carbon manganese steel (C-Mn steel), belonging to the category of non-alloy steel. In its designation, "P" represents pressure vessel applications, "265" indicates a minimum yield strength of 265 MPa, and "G" and "H" respectively emphasize manganese strengthening and high-temperature suitability.
What is the ASTM equivalent of P265 GH?
China (GB): 20G (Boiler steel, GB 713).
USA (ASTM): SA-516 Gr.60/65 (Similar yield strength).
What is P265GH material?
P265GH steel is a high-strength, low-alloy structural steel material of European standard, which has the characteristics of maintaining good mechanical properties at high temperatures and excellent low-temperature toughness.
P265GH Chemical Composition
The chemical composition of P265GH steel plate mainly includes elements such as carbon (C), silicon (Si), manganese (Mn), phosphorus (P), and sulfur (S), with the specific contents as follows:
Carbon (C): ≤0.20%
Silicon (Si): ≤0.40%
Manganese (Mn): 0.80%～1.40%
Phosphorus (P): ≤0.025%
Sulfur (S): ≤0.010%
In addition, it also contains alloying elements such as chromium (Cr), nickel (Ni), molybdenum (Mo), niobium (Nb), vanadium (V), aluminum (Al), and copper (Cu), but the contents are limited; for example, chromium (Cr) and nickel (Ni) are both ≤0.30%.
P265GH Physical Properties
