SAF Alin 182 description: Basic-coated MMA electrode for welding high-temperature creep-resistant, heat resistant and corrosion resistant Ni-Cr alloys. Cryogenic toughness down to -196C, creep resistant < 800C, non-scaling < 1000C. In sulphurous atmosphere the weld metal can be used up to 500C. Even at higher temperatures, there is only limited carbon diffusion in the weld metal thus avoiding crack-prone carbides at the weld interface of dissimilar joints. The weld metal coefficient of thermal expansion is between austenitic and ferritic steels, therefore ALIN 182 is used for joining ferritic to austenitic steels, dissimilar joints, with operating temperatures or postweld heat treatment > 300C.
