Channel Steel
Mechanical properties difference between S355JR and S355J0 steel:
| 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 | ||||
| S355JR | 355 | 450-680 | 22 | 20 | 27 |
| S355J0 | 355 | 450-680 | 22 | 0 | 27 |
In S355JR and S355J0 steel, JR and J0 indicates the steel needs to do +20℃ impact test and 0℃ impact test respectively. The different impact temperature is the main difference between S355JR and S355J0 steel. S355JR steel can better adapt to higher temperature work condition than S355J0 steel.
