1(7) S European Standard Steel S EN 10025 : 2004 Standard Plate S structural steel plate is a highstrength lowalloy European standard structural steel covering four of the six "Parts" within the EN 10025 2004 standard. With imum yield of 50,000 KSI, it meets requirements in chemistry and physical properties similar to ASTM A572 / 709. Careful attention should always be placed on the specific variation of S required if considering substitute material. S is used in almost every facet of structural fabrication. Typical applications include: Structural steelworks: bridge components, components for offshore structures Power plants Mining and earthmoving equipment Loadhandling equipment Wind tower components Part 2 NonAlloy s E...
