Is S275JR equivalent to ASTM A36 or not
Mechanical properties of S275JR carbon steel plate and ASTM A36 plates:
| Grade | Yield strength ReH/(N/mm2) (t≤16mm) min | Tensile strength Rm/(N/mm2) (3mm≤t≤16mm) | Elongation A/% (3mm≤t≤40mm) min | Charpy V test | |
| Temperature/℃ | Impact energy (Longitudinal)/J min | ||||
| A36 | 250 | 400-550 | 23 | - | - |
| S275JR | 275 | 410-560 | 23 | 20 | 27 |
ASTM A36 plates have a min. yield strength of 250 MPa and S275JR carbon steel plate has a yield of 275 MPa. And the tensible strength of S275JR carbon steel plate is also little higher than that of ASTM A36 plates. So it is not right to say "S275JR equivalent to ASTM A36".
