Nickel Based Alloy

ES Ni 70 A5.11: ENiCrFe-3 / ENISO 14172:2006: E Ni 6082


ES Ni 70 Basic electrode, core wire alloyed, corresponding to DIN EL-NiCr 19 Nb for high-grade welding of nickel base alloys, high-temperature and creep resisting steels, heat resisting and cryogenic materials, low-alloyed problem steels and dissimilar joints. Ferritic-austenitic joints for service temperatures above +300°C or for applications where a post weld heat treatment is required .<br> High manganese of this weld deposit reduces the possibility of micro fissures but reduces creep strength which limits its usage up to 900°F (482°C) . Excellent welding characteristics in all positions except vertical-down, easy slag removal, high resistance to porosity, absence of undercuts, high degree of purity. Electrode and weld metal meet highest quality requirements.

ES Ni 70 is particularly used for pressure vessel fabrication for -196°C to +650°C, otherwise up to the scaling resistance temperature of +1200°C (S-free atmosphere). Insusceptible to embrittlement, highly resistant to hot cracking, furthermore, C-diffusion at high temperature or during heat treatment of dissimilar joints is largely reduced. Thermal shock resistant, stainless, fully austenitic.<br> Used for welding nickel-chromium-iron alloys to themselves , Used for dissimilar welding between nickel-chromium-iron alloys to mild steel or stainless steel
