Enforce Standards and Chemical Compositions
ASME SA612 Pressure vessel plate complies with ASME SA612/SA612M standards. Its chemical composition is strictly controlled to ensure the excellent performance of the steel plate. The main chemical composition includes elements such as carbon (C), silicon (Si), manganese (Mn), and possible alloying elements such as chromium (Cr), nickel (Ni), niobium (Nb), etc. The specific chemical composition control is as follows:
Carbon (C) content: ≤0.25%
Silicon (Si) content: between 0.15% and 0.5%
Manganese (Mn) content: between 1.0% and 1.5%
Phosphorus (P) and sulfur (S), as impurity elements, are controlled at a low level of ≤0.025%
