BÖHLER FOX E 308 H不锈钢焊条

BÖHLER FOX E 308 H不锈钢焊条

Description
Rutile-basic coated, core wire alloyed electrode for the use of high temperature CrNi austenitic
steel for service temperatures up to +700 °C. Specially designed for the base metal AISI 304H
(W. no. 1.4948). Controlled ferrite content of 3-8 FN. The deposit is insusceptible to embrittle-
ment and scaling. Excellent weldability in all position except vertical down.
