CATEGORY

TYPE

Medium alloyed seamless basic flux cored wire for SAW

APPLICATIONS

Crane, apparatus, pressure vessels, foundries, casting etc.

PROPERTIES

Extreme crack resistant weld metal due to the high basic slag in combination with a remarkable low hydrogen content. The requirements of the steels mentioned are obtained in normalized (N) and in air quenched (A) condition . SA 1.41 B is not recommended in the stress relieved condition.
