S275JR equivalent grades: ASTM, EN, JIS, GB, DIN
S275JR is non-alloy hot-rolled structural steel specified in EN 10025-2. What follows is the substitution list: 5 standard systems, and for each candidate the clause that makes it an exact match or stops it being one. The full S275JR data sheet carries the composition and mechanical tables.
Last updated
A single clause separates A572 Gr. 42, Q275B, IS 2062 E275 BR: differ either a test temperature or a composition bound that the other does not. At the functional level A36, S235JR, S355JR and 4 more serve as a replacement once the design has been re-run. The table holds 2 in ASTM / ASME, 1 in GB/T (China), 2 in IS (India), 4 in EN (European), 1 in JIS (Japan).
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. |
| E250 | IS (India) | Functional | Matches on tensile — S275JR is 410–560 MPa — but E250's yield is 250 MPa against 275. Where the design is tensile-governed the substitution works; where it is yield-governed it does not. |
| SS400 | JIS (Japan) | Functional | Yield 245 MPa, below S275; SM400 is closer on impact but also 245 MPa. |
Identical, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
