Characteristics and field of use
Core wire alloyed, low-carbon, austenitic stick electrode with rutile coating. High crack resistance with hard-to-weld materials, austenite-ferrite joints and weld claddings is achieved through the increased ferrite content (FN ~17) in the weld metal. Particularly good fine welding properties and excellent AC weldability characterise this product. For operating temperatures between -60°C and +300°C, for the first layer of weld claddings up to +400°C.

Base materials
Joints of and between high-strength, unalloyed and alloyed quenched and tempered steels, stainless, ferritic Cr and austenitic Cr-Ni steels, austenitic manganese steels and weld claddings: for the first layer of chemically resistant weld claddings on the ferritic-pearlitic steels used for boiler and pressure vessel construction up to fine-grained structural steel S500N, and for the creep resistant fine-grained structural steels 22NiMoCr4-7, 20MnMoNi5-5 and GS-18NiMoCr 3 7
