S235JR equivalent grades: ASTM, EN, JIS, GB, DIN

Cross-reference for S235JR across standard systems. Each match is graded so you can see how safe the substitution is. Non-alloy hot-rolled structural steel — full S235JR 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.

S235JR in DIN (superseded German)

• St37-2 — Identical Direct successor (1.0038). S235JR guarantees 27 J at +20 °C which St37-2 did not; ordering S235JR always satisfies an St37-2 requirement.

S235JR in EN (European)

• S235JRH — Identical Same steel as flat/long product to EN 10025-2; the H suffix only marks the hollow-section delivery standard.
• S235J0 — Near Same chemistry limits with P/S 0.030 %; impact 27 J at 0 °C instead of +20 °C.
• S195T — Near The strip from which most S195T tube is actually made; S235JR coil certified to EN 10255 requirements.
• S275JR — Functional Next strength class (275 MPa); substitutes upward for strength but is not identical.
• C15 — Functional Structural steel of similar carbon; not a case-hardening quality (no hardenability or cleanliness control).
• DC01 — Functional Hot-rolled structural steel of similar chemistry; not a cold-rolled forming grade and not interchangeable in surface or gauge.
• DD11 — Functional Structural steel of similar chemistry with guaranteed 235 MPa yield and impact; DD11 has no minimum yield guarantee for structural design.
• S250GD — Functional Uncoated hot-rolled structural steel of similar strength for members that will be post-galvanized.

S235JR in ASTM / ASME

• A36 — Near A36 yield 250 MPa (36 ksi) and Rm 400–550 MPa are slightly higher; no impact requirement. Widely accepted as the US counterpart.
• A283 Gr. C — Near Yield 205 MPa, Rm 380–515 MPa; plate only, no Charpy requirement.

S235JR in GB/T (China)

• Q235B — Near GB/T 700 Q235B: yield 235 MPa, Rm 370–500 MPa, 27 J at +20 °C — the closest Chinese match; C max 0.20 %.

S235JR in GOST (Russia/CIS)

• St3sp — Near GOST 380 St3sp (killed): yield 245 MPa ≤ 20 mm, Rm 370–480 MPa; impact tested at +20 °C.

S235JR in IS (India)

• IS 2062 E250 BR — Near Yield 250 MPa, Rm 410 MPa min; BR = impact tested at room temperature.

S235JR in JIS (Japan)

• SS400 — Near JIS G3101 SS400: yield 245 MPa (≤16 mm), Rm 400–510 MPa; no chemistry limits beyond P and S, no impact test.

Superseded names for S235JR

• St37-2 — DIN 17100 (withdrawn 1994): Most common legacy name; still on many drawings and in Turkish, Polish and Middle-East specifications.
• Fe360B — EN 10025:1990 / UNI 7070: Renamed S235JR in EN 10025:1993.
• 40A / 40B — BS 4360 (withdrawn 1994): 40B is the closer match (impact at +20 °C).
• E24-2 — NF A 35-501 (withdrawn): French designation.
• S235JRG2 — EN 10025:1993: Fully killed variant; merged into S235JR (1.0038) in EN 10025-2:2004.
