Synthetic electrode for difficult to weld steels
Descripción y aplicaciones
Synthetic electrode with high recovery (160%). With a rutile coating, for overlaying and welding high strength steels with each other and with stainless steels. Also recommended for buffer layers before hardfacing and to weld galvanised steels.
Highly resistant against cracks. Offers soft fusion, very little spatters, self releasing slag.
