S195T equivalent grades: ASTM, EN, JIS, GB, DIN
Cross-reference for S195T across standard systems. Each match is graded so you can see how safe the substitution is. Non-alloy steel for welded and threaded tubes (water, gas, sprinkler, GI pipe) — full S195T data sheet.
Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| A53 Grade A (Type E/F) | ASTM / ASME | Near | ASTM A53 Grade A: 205 MPa yield, 330 MPa tensile, welded or seamless, black or galvanized — the US water/gas pipe; Grade B (240/415) is stronger and usually what is stocked. |
| S235JR | EN (European) | Near | The strip from which most S195T tube is actually made; S235JR coil certified to EN 10255 requirements. |
| Q195 / Q235 (GB/T 3091) | GB/T (China) | Near | Chinese welded pipe for low-pressure liquid delivery on Q195–Q235 steel. |
| Ст2сп / Ст3сп (GOST 3262) | GOST (Russia/CIS) | Near | GOST 3262 water-gas pipe (ВГП, обыкновенная/усиленная) on Ст2–Ст3 steel: the CIS equivalent of medium/heavy series. |
| SGP (JIS G3452) | JIS (Japan) | Near | JIS G3452 carbon steel pipe for ordinary piping, Rm ≥ 290 MPa; galvanized SGP-W. |
| S235JRH | EN (European) | Functional | Structural hollow-section grade (EN 10219) with 235 MPa yield — the alternative when the pipe is a column or frame member, not a pressure line. |
| P235TR1 | EN (European) | Functional | EN 10217-1 pressure-purpose welded tube with specified elevated-temperature use; choose when the line is above 50 bar or a pressure code applies. |
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.
