GB 713 boiler steel">GB 713 boiler steel material 14Cr1MoR pressure vessel steel plates are special steel materials for pressure vessels, and they belong to Cr-Mo hydrogen resistant steel. During the production of GB 713 14Cr1MoR pressure vessel steel plates, the manufacture should strictly control the fluctuation range of chemical composition, strictly control harmful elements such as P, S, Sn, Sb, As, Cu, reduce cold embrittlement and temper embrittlement tendency, and improve the corrosion resistance of 14Cr1MoR steel.
GB 713 boiler steel material 14Cr1MoR pressure vessel steel plates chemical composition ( max, %):
| GB713 | C | Si | Mn | Cu | Ni | Cr | Mo | P | S |
| 14Cr1MoR | ≤0.17 | 0.50-0.80 | 0.40-0.65 | ≤0.30 | ≤0.30 | 1.15-1.50 | 0.45-0.65 | ≤0.020 | ≤0.010 |
GB 713 boiler steel material 14Cr1MoR pressure vessel steel plates mechanical property:
| GB713 | Thickness， in mm | Tensile Strength | Yield Strength， min | Elongation， %， min | Temperature | Impact energy (J) |
| 14Cr1MoR | 6<T≤100 | 520-680 | 310 | 19 | 20 | 47 |
| 100<T≤200 | 510-670 | 300 |
GB 713 boiler steel material 14Cr1MoR pressure vessel steel plates are widely used to manufacture petrochemical, nuclear power, steam turbine cylinder blocks, thermal power and other high-temperature and high-pressure large-scale equipment in contact with hydrogen or hydrogen mixed media.
