A516 Grade 70 equivalent grades: ASTM, EN, JIS, GB, DIN

Cross-reference for A516 Grade 70 across standard systems. Each match is graded so you can see how safe the substitution is. Carbon steel plate for pressure vessels, moderate and lower temperature — full A516 Grade 70 data sheet.

Cross-reference table

Identical = same composition and mechanical limits within rounding. Near = one limit differs (e.g. carbon max or impact temperature). Functional = interchangeable for most uses after an engineering check.

How the matches are graded

Identical means the chemical composition windows overlap so that material certified to one specification meets the other without deviation, and the mechanical minimums are the same or the other is inside them — mills usually dual-certify. Near means one limit differs (a carbon maximum, an impact temperature, a strength minimum or a delivery condition) and a substitution needs a one-line engineering check. Functional means the grades serve the same purpose but are not the same steel — a designer can often use one for the other, but only after re-checking the design.

A516 Grade 70 in ASTM / ASME

• A516 Gr. 60 — Near Same spec, lower strength (220 MPa / 415–550 MPa); chosen for better toughness and formability.
• A537 Cl. 1 — Near Normalized C-Mn-Si plate, yield 345 MPa — the upgrade when A516-70 is not strong enough.
• A36 — Functional Structural plate without pressure-vessel quality (grain size, testing, chemistry control) — not accepted for ASME pressure parts except by special provisions.

A516 Grade 70 in EN (European)

• P295GH — 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 — 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 — Near 355 MPa grades exceed A516-70 yield; used when a European mill supplies a Grade 70 design.

A516 Grade 70 in GB/T (China)

• Q345R — 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.

A516 Grade 70 in GOST (Russia/CIS)

• 16GS / 17GS / 20K — Near GOST 5520 boiler plates: 16GS (yield 265–295, Rm 460–490), 17GS (345 / 490), 20K (245 / 410).

A516 Grade 70 in IS (India)

• IS 2002 Gr. 2 / Gr. 3 — Near IS 2002 grade 2 (yield 240, Rm 410–530) and 3 (yield 290, Rm 490–610).

A516 Grade 70 in JIS (Japan)

• SB450 / SPV315 — Near JIS G3103 SB450 boiler plate (yield 245, Rm 450–590) and G3115 SPV315 (yield 315, Rm 490–610) bracket A516-70.

Superseded names for A516 Grade 70

• K02700 (Gr 70), K02403 (Gr 60), K02800 (Gr 65), K01800 (Gr 55) — UNS
• SA-516 — ASME BPVC Section II Part A: ASME adoption — identical to A516 with ASME editorial changes; the form used on vessel drawings.
• A515 — ASTM A515: Sister spec for intermediate/higher temperature (coarse-grain Si-killed); A516 replaced it for most work.
• A285 Gr. C — ASTM A285: Lower-strength, lower-quality vessel plate for low-pressure tanks.
• BS 1501-224 Gr 490 — BS 1501 (withdrawn): British counterpart.
