ASTM's steel standards are instrumental in classifying,evaluating,and specifying the material,chemical,mechanical,and metallurgical properties of the different types of steels,which are primarily used in the production of mechanical components,industrial parts,and construction elements,as well as other accessories related to them.Structural Steel - S235,S275,S355 Chemical Composition May 11,2012·For example,S355K2W is a structural steel that has been hardened,denoted by K2,and has been designed with a chemical composition to withstand increased weathering - W.Therefore,this grade of structural steel will have a slightly different chemical composition to the standard S355 grade.
