S275JR equivalent grades: ASTM, EN, JIS, GB, DIN
Cross-reference for S275JR across standard systems. Each match is graded so you can see how safe the substitution is. Non-alloy hot-rolled structural steel — full S275JR data sheet.
Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| A572 Gr. 42 | ASTM / ASME | Near | Yield 290 MPa (42 ksi), Rm 415 MPa min — slightly stronger, HSLA chemistry. |
| Q275B | GB/T (China) | Near | GB/T 700 Q275: yield 275 MPa, Rm 410–540 MPa; B = 27 J at +20 °C. |
| IS 2062 E275 BR | IS (India) | Near | Yield 275 MPa, Rm 430 MPa min, room-temperature impact. |
| A36 | ASTM / ASME | Functional | A36 yield 250 MPa is below 275 MPa; A36 is not a drop-in replacement where the design used fy = 275. |
| S235JR | EN (European) | Functional | Lower class; S275JR can replace S235JR, not vice versa. |
| S355JR | EN (European) | Functional | Higher class; same delivery conditions. |
| P265GH | EN (European) | Functional | Structural steel of similar strength without elevated-temperature or pressure-equipment certification (no PED compliance). |
| S280GD | EN (European) | Functional | Uncoated hot-rolled equivalent by yield for members that will be hot-dip galvanized after fabrication. |
| SS400 | JIS (Japan) | Functional | Yield 245 MPa, below S275; SM400 is closer on impact but also 245 MPa. |
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.
