S420G2+M steel plate under EN10225 standard, it is a kind of high tensile and high yield steel. S420G2+M offshore platform steel plate is widely used in the construction of oil rigs and offshore service platforms.
EN10225 S420G2+M Offshore Platform Steel Plate is mainly used to Offshore Structural and Ocean Marine drilling platform.
S420G2+M high strength steel plate also named as S420G2+M high strength oil and offshore platform steel plate under steel stand EN 10225.S420G2+M shall be done low temperature impacting test under minus 40 centigrade, and the minimum energy value shall be above 50J. When rolling oil and offshore steel plate S420G2+M, the heat treatment TMCP shall be done for each steel plate.
