GB 713 15CrMoR pressure vessel steel plates">pressure vessel steel plates are Chinese boiler quality steel with good heat resistance. As the name implies, 15CrMoR pressure vessel steel plates belong to chromium molybdenum steel. Boiler quality GB 713 15CrMoR pressure vessel steel plates are suitable for pressure parts of boilers and pressure vessels for medium and normal temperature service.
Boiler quality GB 713 15CrMoR pressure vessel steel plates chemical composition ( max, %):
| C | Si | Mn | Cu | Ni | Cr | Mo | P | S |
| 0.08-0.18 | 0.15-0.40 | 0.40-0.70 | ≤0.30 | ≤0.30 | 0.80-1.20 | 0.45-0.60 | ≤0.025 | ≤0.010 |
Boiler quality GB 713 15CrMoR pressure vessel steel plates mechanical property:
| GB 713 | Thickness, in mm | Tensile Strength | Yield Strength, min | Elongation, %, min |
| 15CrMoR | 6<T≤60 | 450-590 | 295 | 19 |
| 60<T≤100 | 275 | |||
| 100<T≤200 | 440-580 | 255 |
Generally, boiler quality GB 713 15CrMoR pressure vessel steel plates are delivered under normalizing and tempering condition. Upon agreement between the supplier and buyer, 15CrMoR steel plates above 60mm in thickness can also be supplied in annealing or tempering condition, or in the condition of accelerated cooling and tempering after normalizing. Usually, the 15CrMoR steel plates thickness is within 200mm but above 6mm.
