S275JR Mild steel plate normally rolled under AS rolled. For the heavy thickness steel plate S275JR or want a high steel property, BBN STEEL suggest adopt Normalize heat treatment when rolling.
S275JR Chemical Composition (max %):
| Grade | C% | Si % | Mn % | P % | S % | N % | Cu % |
| S275JR | 0.25 | - | 1.60 | 0.045 | 0.045 | 0.014 | 0.60 |
S275JR Mechanical Properties：
| Grade | Thickness (mm) | Min Yield (Mpa) | Tensile (Mpa) | Elongation (%) | Min Impact Energy | |
| S275JR | 8mm-100mm | 235Mpa-275Mpa | 450-630Mpa | 21-23% | 20 | 27J |
| 101mm-200mm | 205-225Mpa | 450-600Mpa | 19% | 20 | 27J | |
| 201mm-400mm | 195-205Mpa | - | - | 20 | 27J | |
| The min impact energy is longitudinal energy | ||||||
Else, the steel stamped shall also contain specifications (Thickness*Width*Length), Mill’s Logo, Heat number or Batch number according to the original mill test certificates. Customers should choose whether doing Normalized according to the end usage of steel plate S275JR.
