P265GH equivalent grades: ASTM, EN, JIS, GB, DIN
P265GH is non-alloy steel for pressure purposes with elevated-temperature properties specified in EN 10028-2. Substitutes are collected here from 6 standard systems; the grading column says whether a certificate covers the swap or an engineer has to. The full P265GH data sheet carries the composition and mechanical tables.

Mills routinely dual-certify P265GH as Q245R, IS 2002 Gr. 2, SB410 — the limits sit inside each other in both directions. A516 Gr. 60, A516 Gr. 65, A516 Grade 70 and 3 more differ by one requirement, which is a line on the order rather than a redesign. At the functional level A285 Gr. C, 16Mo3, S275JR serve as a replacement once the design has been re-run. The table holds 1 in GB/T (China), 1 in IS (India), 1 in JIS (Japan), 4 in ASTM / ASME, 4 in EN (European), 1 in GOST (Russia/CIS).
Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| Q245R | GB/T (China) | Identical | GB/T 713 Q245R: yield 245 MPa, Rm 400–520 MPa, 31 J at 0 °C; C ≤ 0.20, Mn 0.50–1.10 — the Chinese boiler and pressure-vessel plate matching P265GH/HII. |
| IS 2002 Gr. 2 | IS (India) | Identical | IS 2002 Grade 2 pressure-vessel plate: yield 240 MPa, Rm 410–530 MPa. |
| SB410 | JIS (Japan) | Identical | JIS G3103 SB410 boiler plate: yield ≥ 225 MPa, Rm 410–550 MPa, C ≤ 0.24; SPV235 (G3115) is the pressure-vessel equivalent. |
| A516 Gr. 60 | ASTM / ASME | Near | ASTM A516 Grade 60 (SA-516-60): yield 220 MPa (32 ksi), Rm 415–550 MPa; C ≤ 0.21–0.27 by thickness, no elevated-temperature yield table (ASME Section II-D gives allowables). Closest US boiler-plate grade. |
| A516 Gr. 65 | ASTM / ASME | Near | Yield 240 MPa, Rm 450–585 MPa — slightly stronger than P265GH. |
| A516 Grade 70 | ASTM / ASME | Near | Yield 265 MPa, Rm 410–530 MPa — the EN grade most often substituted for A516-60/65; slightly weaker than Grade 70. |
| P235GH | EN (European) | Near | 1.0345 (ex HI): yield 235 MPa, Rm 360–480 MPa — the lower class; common for tubes. |
| P295GH | EN (European) | Near | 1.0481 (ex 17Mn4): yield 295 MPa, Rm 460–580 MPa. |
| 16K / 20K | GOST (Russia/CIS) | Near | GOST 5520 16K (yield 245, Rm 400–490) and 20K (yield 245, Rm 410–520): Russian boiler plates. |
| A285 Gr. C | ASTM / ASME | Functional | Yield 205 MPa, Rm 380–515 MPa; lower-quality pressure plate for low-pressure vessels. |
| 16Mo3 | EN (European) | Functional | Mo-alloyed step for service above 400–450 °C. |
| S275JR | EN (European) | Functional | Structural steel of similar strength without elevated-temperature or pressure-equipment certification (no PED compliance). |
Identical, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
