Product Description

APPLICATION:

Steel susceptible to heavily loaded, welded structural constructions, e.g. of cranes, bridges, buildings, tankers, water tanks, and floodgates, operating safely at both room and reduced temperatures.

TECHNOLOGICAL INFORMATION:

The steel manufacturer meticulously selects the type and concentration of alloying elements (up to the specified values) to ensure the desired properties. The semi-finished products are delivered pre-toughened and do not require heat treatment at the buyer's location. Stress relieving after welding should be performed under conditions that maintain the mechanical properties of the steel.
