Pourquoi choisir cette électrode basique?
Electrode en emballage sous vide de 5 ou 6Kg pour le soudage des assemblages en acier (carbone et carbone manganèse) fortement sollicités (résistance à la traction jusqu’à 510 MPa).
Elle se caractérise par d’excellentes propriétés mécaniques, en particulier aux basses températures.
