AA B690 FCAW Flux-Cored




AA B690

 
CATEGORY 
TYPE 
Seamless, high-strength flux-cored wire for M21 with basic slag
APPLICATIONS 
Crane-, plant-, craft- and steel construction, pipe work, foundries
PROPERTIES 

Absolutely crack resistant weld metal conditioned by the high-basic slag in combination with extreme low hydrogen content. Therefore, suitable for the economic processing of high-strength, low temperature fine-grained structural steels with R p0,2 >690 N/mm. X-ray-proof seams with low spatter loss. Stable, mechanical property values of the weld metal also at high heat input up to 18 kJ/cm
