Benennung Description Dénomination
Analysis - Value in % / Use C = 0,07, Si = 0,5, Mn = 1,1 For connection and application welding, especially for steel with low purity and higher carbon content. Weldable with direct current, electrode connected to plus terminal (+). No vertical seams C = 0,05, Si = 0,4, Mn = 1,5, Cr = 0,4, Ni = 2,0, Mo = 0,5 For welding, which require high viscosity and crack resistance. Use for high tensile refined fine-grained steel. Very low hydrogen content in weld metal. Weldable with direct current, electrode connected to plus terminal (+). No vertical seams C = 0,1, Si = 0,7, Mn = 6,5, Cr = 18,8, Ni = 8,8 For connections between various alloyed and steel which is difficult to weld. Weldable with direct current, electrode connected to plus terminal (+). No vertical seams
