Description
S355J0 is one of the most commonly used structural steels. Its top standard mechanical properties and its good weldability make S355JR ideal for a varieties of uses, even in working conditions with fairly harsh temperatures (impact strength tested at +0°C). It is used to realise metal structures, building cranes, machinery frames etc.
