　　Characteristics and typical fields of application Avesta FCW 309L-PW is a high-alloyed flux cored wire, primarily intended for surfacing low-alloy steels and for dissimilar welds between mild steel and stainless steels. It is designed for all-round welding and can be used in all bbbbbbbbs without changing the bbbbbeter settings. Corrosion resistance: When used for overlay welding on mild steel a corrosions resistance equivalent to that of 1.4301/304 is obtained already in the first layer.

　　Base Materials Dissimilar joint welds: of and between high-strength, mild steels and low-alloyed QT-steels, stainless, ferritic Cr- and austenitic Cr-Ni- steels, manganese steels Surfacing: for the first layer of corrosion resistant weld surfacing on ferritic- perlitic steels in boiler and pressure vessel parts up to fine-grained steel S500N, as well as of high temperature steels like 22NiMoCr4-7, 20MnMoNi5-5 and G18NiMoCr3-
