S620QL STEEL PLATE,EN10025-6 S620QL
Source:Yusheng steel
EN 10025_6 Steel Grade S620QL is a high yield strength steel which mainly used to built bridges,high buildings,
high strength prevent tanks and other steel structures. Steel plate S620QL owned the minimum yield strength
shall be at 620 Mpa,and the tensile strength shall be within 700_890 Mpa for the plates thickness belows 50mm.
Till now,Yusheng steel can offer this steel plates S620QL in condition Quenched and tempered,our rolling
thickness should be within 6mm_350mm for this steel.The width shall be from 1500mm_4200mm,owning to we
have the widest roller in China.The length range shall be from 5000mm_18000mm.For the small sizes of plates,
we can offer cutting and welding services in our processing plants in Wuyang steel and Shanghai processing plant.
