Highly alloyed welding wire is made in accordance with DSTU EN ISO 14343, AWS A5.9 and GOST 2246-70 from corrosion, heat-resistant and heat-resistant steels. These types of welding wires are used for welding austenitic steels, steels with limited weldability, such as heat-hardening, armor, spring, tool and other steels with a high carbon equivalent. They are also used for surfacing of buffer layers for subsequent hardening surfacing of a wear-resistant layer and restorative surfacing on steel with limited weldability. Welds are characterized by high resistance to high temperatures, as well as high corrosion resistance.
