Supplied to the offshore industry as a structural steel grade, S420G2 is a high tensile and high yield steel used in the construction of oil rigs and offshore service platforms.
Complying with EN10025:2001, the material is supplied as either S420G2+M (thermo–mechanically rolled) or S420G2+Q (Quenched). We supply offshore marine grades from stock or directly shipped from the mill to clients around the world.
Please refer to the technical information for both grades below.
