The ASTM A662 standard, which specifies requirements for carbon-manganese-silicon steel pressure vessel plates for use in medium- and lower-temperature service, covers three grades of carbon-manganese-silicon steel plates, which are primarily used in welded pressure vessels, particularly in applications where improved low-temperature notch toughness is required.
ASTM A662 GR.A GR.B GR.C Chemical Composition and Technical Property is as below:
Standard | C % max | Si max | Mn max | P max | S max | Cr max | Ni max | Cu max | Mo max | tensile strength（MPa） | yield strength（MPa） | Elongation% |
A662 GR.A | 0.29 | 0.13-0.55 | 0.92-1.62 | 0.035 | 0.025 | 0.29 | 0.28 | 0.38 | 0.09 | 400-500 | ≥250 | ≥21 |
A662 GR.B | 0.29 | 0.13-0.55 | 0.92-1.62 | 0.035 | 0.025 | 0.29 | 0.28 | 0.38 | 0.09 | 450-585 | ≥250 | ≥21 |
A662 GR.C | 0.29 | 0.13-0.55 | 0.92-1.62 | 0.035 | 0.025 | 0.29 | 0.28 | 0.38 | 0.09 | 485-620 | ≥250 | ≥21 |
