ER309LSi
Characteristics and typical fields of application
Stainless. Well suited for depositing intermediate layers when welding cladded materials. Favorably high Cr and Ni contents, low C content. For joining unalloyed/low-alloy steels/cast steel grades or stainless heat resistant Cr steels / cast steel grades to austenitic steels / cast steel grades. For depositing intermediate layers when welding the side of plates clad with low-carbon – non stabilized or stabilized – austenitic CrNiMo(N) austenitic metals. Application temperature max. 300°C (572 °F).
Base materials
Joints of and between HSLA, unalloyed and alloyed quenched and tempered, stainless, ferritic Cr
and austenitic CrNi steels, high manganese steels as well as weld claddings for the first layer of
chemical resistant weld claddings on ferritic-pearlitic steels up to fine grained structural steel
S500N for steam boiler and pressure boiler constructions, as well as on creep resistant fine grained
structural steels 22NiMoCr4-7 acc. to leaflet “SEW-Werkstoffblatt” No. 365, 366, 20MnMoNi5-5 and
