Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| A572 Gr. 50 | ASTM / ASME | Near | Yield 345 MPa (50 ksi), Rm 450 MPa min; HSLA with Nb/V, no impact requirement unless supplementary S5 is ordered. |
| A992 | ASTM / ASME | Near | Yield 345–450 MPa, Rm 450 MPa min; shapes only, with a yield/tensile ratio cap of 0.85. |
| St52-3 | DIN (superseded German) | Near | Successor of St52-3 U (impact at +20 °C). |
| S355J2 | EN (European) | Near | Same strength; impact at −20 °C, P/S ≤ 0.025 %, fully killed. |
| Q355B | GB/T (China) | Near | GB/T 1591 Q355B: yield 355 MPa, Rm 470–630 MPa, 34 J at +20 °C — the direct successor of Q345B and the closest Chinese match. |
| 09G2S | GOST (Russia/CIS) | Near | GOST 19281 09G2S: yield 325–345 MPa, Rm 470–490 MPa; low-alloy Mn-Si steel, better cold toughness. |
| IS 2062 E350 BR | IS (India) | Near | Yield 350 MPa, Rm 490 MPa min, room-temperature impact. |
| SM490A | JIS (Japan) | Near | JIS G3106 SM490A: yield 325 MPa (≤ 16 mm), Rm 490–610 MPa; A = no impact requirement, B = 27 J at 0 °C. |
| S275JR | EN (European) | Functional | Higher class; same delivery conditions. |
| S350GD | EN (European) | Functional | Uncoated hot-rolled equivalent by yield, for profiles hot-dip galvanized after forming. |
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.
