LH 1181S
High strength basic electrode
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.
