USE OF AN ALLOY AS WELDING FILLER MATERIAL

摘要

1. The use of an alloy consisting in percent by weight of : C to 0.05 Si 0.1 to 1.1 Mn 1.0 to 7.0 Cr 18.0 to 22.5 Mo 4.0 to 7.0 Ni 23.0 to 27.0 Cu 1.6 to 3.0 N 0.05 to 0.3 optionally W 0.1 to 2.0 optionally V 0.01 to 1.5 Co 0 to 3.8 Ti 0 to 0.5 Nb 0 to 1.0 optionally Ce and/or La 0.01 to 0.4, remainder iron and impurities caused by production, as a welding filler material for bonding high-temperature or heat-resisting steels to unalloyed steels or low-alloy steels, with exposure to corrosion, in particular by sulphur oxyacids of differing concentration and temperature.
