CSS 307S
Stainless steel electrode for repair and reloading.
Product description
High-efficiency rutilo-basic electrode (160%), depositing austenitic manganese stainless steel. Used for assemblies and hardfacing of manganese steels up to 14% Mn, heterogeneous assemblies between steels of different grades and all steels that are difficult to weld, as an undercoat prior to hardfacing. Repair of all parts subject to impact.
Ease of use, smooth melting, low spatter, self-removing slag and excellent bead appearance. Good resistance to cracking, easy machining when not work-hardened. Pressure- and friction-hardenable deposit (rails, switches, etc.).
Public works, rails, railroads, cement works, armor plates, excavator buckets, crusher jaws, etc.
