S355J2-steel_4448.html target=_blank class=infotextkey>S355JR grade steel is an important material used in structural engineering. It gives excellent yield and tensile strength normally supplied with various treatments and test, to make sure it is a wise option to use in different industries and projects.
EN10025 European Standard Structural Steel
EN 10025 is the European standard structural steel for Hot rolled products in carbon steel. S355 grade is also defined in this standard, other than this grade there are also S235, S275, S460, S550, S620, S690 with conditions hot rolled, normalized, quenched, and tempered.
