TECHNICAL REQUIREMENTS:GOST 9466-75, TU BY 100034500.015-2006

COATING: main

PURPOSE:

Welding of critical structures of the corrosion-resistant steels hromonikelemolibdenovyh 10X17H13M2T, 10H17N13M3T, 08H21N6M2T and the like operating at temperatures up to 350C when the weld metal to the strict requirements for resistance to intergranular corrosion. In all spatial positions except the vertical downward direct current reverse polarity.
