ATOM ARC 7018-Mo
El Atom Arc 7018-Mo es un electrodo E7018-A1 para sodadura fuera de posición bajo en Hidrògeno, recomendado para soldadura de aceros de alta tensiòn de baja aleaciòn, y aceros de 0.5% Mo.
características
Los Electrodos Atom Arc 7018-Mo contienen un 0.5% de Mo. Como aleaciòn adicional. Son recomendados para soldaduras de aceros de alta tensiòn de baja aleaciòn de 50 ksi (345 Mpa), como rendimiento mìnimo de fuerza, y tambièn para tuberìa de acero con 0.5% de Molibdeno. Son usados ampliamente en la fabricaciòn de calentadores de agua, tuberìa de presiòn, y en envases de presiòn para otras aplicaciones.
