Descripción y aplicaciones

Basic coated electrode highly resistant to cracks and elaborated for welding fine grain steels and steels with high mechanical characteristics (Rm up to 800 MPa).

Welds of high security - buffer layer for hardfacing - pleasant fusion, stable arc, low spatters, good removal of the slag and nice aspect of the weld seam.


Construction steels for general use :

NF A 35-501 :A50-2*. A60-2*,3. E36-2*,3*,4*.

DIN 17100 :St50-2*. St60-2*. St70-2*.

ASTM : A678grC*. A709gr50*,100*. A710grA*.


High strength steels:

NF A 36-204 : E500T*.. E550T*. E620T*. E690T*.

DIN 17 102 : StE460, 500* , 590* , 690*.

Also suitable for welding steels destinated to heat treatment like : 15CD4*. 25CD4*. 35CD4*.XC38. XC48*. 32C4....., also for construction steels self - patining (consult us)

(*) eventual preheating and post-weld heat treatment in the case of heavy thickness.
