Characteristics and field of use
UTP 613 Kb is a basis-coated stick electrode for construction-, boiler-, tube- and finegrained
steels as well as for steels with up to 0,35% C-content. It is recommended especially
for the following base metal.
UTP 613 Kb has a good weldability and a stable arc. The weld metal is resistant to ageing,
crack resistant and is little affected by steel impurities.
