A516 Grade 70 equivalent grades: ASTM, EN, JIS, GB, DIN
A516 Grade 70 is carbon steel plate for pressure vessels, moderate and lower temperature specified in ASTM A516. 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 A516 Grade 70 data sheet carries the composition and mechanical tables.
Last updated
A516 Gr. 60, A537 Cl. 1, P295GH and 6 more differ on one limit only — a carbon ceiling, an impact temperature or a strength minimum. Functionally interchangeable, A36 serves a different route to the same duty — check the design, not the analysis. Across systems that is 3 in ASTM / ASME, 3 in EN (European), 1 in GB/T (China), 1 in GOST (Russia/CIS), 1 in IS (India), 1 in JIS (Japan).
Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| A516 Gr. 60 | ASTM / ASME | Near | Same spec, lower strength (220 MPa / 415–550 MPa); chosen for better toughness and formability. |
| A537 Cl. 1 | ASTM / ASME | Near | Normalized C-Mn-Si plate, yield 345 MPa — the upgrade when A516-70 is not strong enough. |
| P295GH | EN (European) | Near | EN 10028-2 P295GH (1.0481, ex 17Mn4): yield 295 MPa, Rm 460–580 MPa, guaranteed yield to 400 °C — strength closest to A516-70; chemistry C ≤ 0.08–0.20 lower. |
| P265GH | EN (European) | Near | Yield 265 MPa, Rm 410–530 MPa — the EN grade most often substituted for A516-60/65; slightly weaker than Grade 70. |
| P355GH / P355NH | EN (European) | Near | 355 MPa grades exceed A516-70 yield; used when a European mill supplies a Grade 70 design. |
| Q345R | GB/T (China) | Near | GB/T 713 Q345R: yield 345 MPa, Rm 510–640 MPa, 31 J at 0 °C — the Chinese pressure plate normally offered for A516-70 (stronger); Q245R ≈ A516-60. |
| 16GS / 17GS / 20K | GOST (Russia/CIS) | Near | GOST 5520 boiler plates: 16GS (yield 265–295, Rm 460–490), 17GS (345 / 490), 20K (245 / 410). |
| IS 2002 Gr. 2 / Gr. 3 | IS (India) | Near | IS 2002 grade 2 (yield 240, Rm 410–530) and 3 (yield 290, Rm 490–610). |
| SB450 / SPV315 | JIS (Japan) | Near | JIS G3103 SB450 boiler plate (yield 245, Rm 450–590) and G3115 SPV315 (yield 315, Rm 490–610) bracket A516-70. |
| A36 | ASTM / ASME | Functional | Structural plate without pressure-vessel quality (grain size, testing, chemistry control) — not accepted for ASME pressure parts except by special provisions. |
Identical, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
