2.Structural S235 and S355 Steel the Mechanical Properties and the Chemical Composition.S235 and S355 steels are intended for welded constructions,carrying and dynamically loaded DESIGN OF STEEL STRUCTURES BASED ON BS59501.3 Chemical composition of structural steel The Chemical composition of Structural Steel is extremely important and highly regulated. S355 0.23 max 1.60 max 0.05 max 0 Poisson Ratio EN 10025 Grade S355J2G3 normalized or normalized formed S355J2G3 is a high-tensile fine grained steel for welding constructions of dynamic load.The steel is applicated up to temperatures of -20°C.Compared to S235J2G3 is achievable a considerable saving of material due to the by 120 MPa higher yield point.The steel shows a by 15% higher resistance to mineral wear due to sliding action in

Chemical composition (%) Description Austenitic-ferritic steel (about 40-50% ferrite) with a high consistance in media that contain chlorine.Due to its high percentage of Cr+Mo,it has an excellent resistance to pitting,fretting and stress corrosion.With its IK-resistance according to DIN 50 914,it is also very suitable for welding.Steel material properties - SteelConstructionfoThe chemical composition for each steel specification is therefore carefully balanced and tested during its production to ensure that the appropriate properties are achieved. the primary designation relates to the yield strength,e.g.S355 steel is a structural steel with a specified minimum yield strength of 355 N Poisson's ratio,poisson ratiopoisson ratioASTM A572 Grade 50 Steel Equivalent,Gr 65,60 Properties ASTM A572 GR 50 steel equivalent European standard is EN 10025-2 S355 steel.ASTM A572 Grade 50 Properties Specification.The following tables show ASTM A572 Grade 50 properties,as well as the specifications of Grade 65,Grade 60,etc.including chemical composition,mechanical properties and equivalent grade.Chemical Composition
