I will buy welding electrodes NIAT-5

I will buy welding electrodes NIAT-5 for welding critical structures made of alloy steels of increased and high strength in a thermally strengthened state without subsequent heat treatment after welding, incl. steel grades 30KhGSA and 30KhGSNA, as well as for welding low-alloy and alloy steels with austenitic steels. Welding in the lower, vertical and limited ceiling positions of the seam with direct current of reverse polarity.
