ASTM A204 is a set of standards developed by the American Society for Testing and Materials (ASTM) that specifies requirements for molybdenum-alloyed steel plates used in the manufacture of welded boilers and pressure vessels.
ASTM A204 GR.A GR.B GR.C Grade Chemical Composition and Technical Property is as below：
Standard | C % max | Si | Mn max | P max | S max | Mo
| tensile strength（MPa） | yield strength（MPa） | Elongation% |
A204 GR.A | 0.18 | 0.15-0.4 | 0.9 | 0.035 | 0.035 | 0.45-0.6 | 450-585 | ≥255 | ≥19 |
A204 GR.B | 0.2 | 0.15-0.4 | 0.9 | 0.035 | 0.035 | 0.45-0.6 | 485-620 | ≥275 | ≥17 |
A204 GR.C | 0.23 | 0.15-0.4 | 0.9 | 0.035 | 0.035 | 0.45-0.6 | 515-655 | ≥295 | ≥16 |
The following are the main application fields of ASTM A204:
Petroleum, chemical industry: for the manufacture of reactors, heat exchangers, separators and other equipment.
Power station: used to manufacture boiler steam ladle, high-pressure piping, etc.
Boiler industry: for the manufacture of boilers and related components.
Nuclear reactor: used to manufacture nuclear reactor pressure vessel.
Liquefied gas and liquefied petroleum gas: for the manufacture of storage and transportation equipment.
Hydroelectric power plants: Used to manufacture high-pressure piping for hydroelectric power plants, etc.
