Description

S355J2 is the structural steel par excellence. The top standard mechanical properties, in particular its excellent impact strength, make S355J2 ideal for use in harsh conditions with particularly low temperatures (up to -20°C). It is suitable for welding. It is used to realise metal structures, building cranes, machinery frames etc.
