This is a hot-rolled pure structural steel. With good plasticity, toughness, and weldability, it has a lower yield strength of 185 – 235MPa. It is equivalent to Fe360B. Any steel with similar chemical and mechanical properties can be designated as S235JR material.
EN 1.0038 material can be made into many steel products, such as H beam, I beam, steel channel, steel plate, steel angle, steel pipe, wire rods, and nails, etc. and these products are widely used in general requirements for welded structures and parts such as bridges, transmission towers, boilers, steel structure factories, shopping centers and other buildings, etc.
