Steel susceptible to heavily loaded, welded structural constructions, e.g. of cranes, bridges, buildings, tankers, water tanks and floodgates, working at room and reduced temperatures.
The steel manufacturer decides on the type and concentration of alloying elements (up to the stated values) ensuring required properties. The semi-finished products are delivered as toughened and are not subject to heat treatment on the buyer's premises. Stress relieving after welding should be done under conditions preventing the reduction of the mechanical properties of steel.
