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. We Limited specialise in the supply of offshore steel products to the global oil and gas industry.
Oil and offshore platform used high strength steel plate S420G2+QT is in steel standard EN 10225. For all thickness,oil and offshore steel plate S420G2+QT need to be done quenched and tempered. Now Katalor can offer the maximum thickness for S420G2+QT steel plates can reach 250mm with quenched and tempered heat treatment. The original mill test certificate shall be issued under format EN10204 3.1 or EN10204 3.2 if customer need the third party inspections.
Thickness:6mm-300mm, Width:1500mm-4200mm, Length:3000mm-18000mm
