ASTM A204 Grade A is used in fabricators serving industry, especially in the oil, gas and chemical supply markets.
For the chemical composition for these three steel grades, A204 Grade A (SA204 Grade A),A204 Grade B(SA204 Grade B) and A204 Grade C(SA204 Grade C),the big different is Carbon contains.Now we give our vast customers our rolling standard properity for steel plate SA204 Grade A as bellows.
Mechanical properties for SA204 Grade A steel plate pressure vessel steel plate:
| Yield strength (Mpa) | Tensile strength (Mpa) | Elongation ≥,% |
