S195T equivalent grades: ASTM, EN, JIS, GB, DIN
S195T is non-alloy steel for welded and threaded tubes (water, gas, sprinkler, GI pipe) specified in EN 10255. Substitutes are collected here from 5 standard systems; the grading column says whether a certificate covers the swap or an engineer has to. The full S195T data sheet carries the composition and mechanical tables.
Last updated
A53 Grade A (Type E/F), S235JR, Q195 / Q235 (GB/T 3091) and 2 more differ on one limit only — a carbon ceiling, an impact temperature or a strength minimum. Functionally interchangeable, S235JRH, P235TR1 serve a different route to the same duty — check the design, not the analysis. Across systems that is 1 in ASTM / ASME, 3 in EN (European), 1 in GB/T (China), 1 in GOST (Russia/CIS), 1 in JIS (Japan).
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, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
