BÖHLER FOX E 347 H不锈钢焊条

BÖHLER FOX E 347 H不锈钢焊条

Description
Basic coated, core wire alloyed electrode for the use of high temperature CrNi austenitic steel
for service temperatures exceeding +400 °C. Specially designed for the base metal AISI 347H.
Controlled ferrite content of 3-8 FN. The deposit is less susceptible to embrittlement and is sca-
ling resistant. Excellent weldability in all position except vertical down.
