SIDER 309LMo Stainless Steel SAW Wire
Filler Metal SIDER 309LMo is designed for welding stainless steels to other types of steel, for dissimilar welds between Cr, Cr-Ni and Cr-Ni-Mo stainless steels and mild steels or low alloys steels, and for depositing buffer layers when welding acid resisting clad steels. The wire offers a high safety against hot cracking even in the case of high dilution.Suitable for service temperatures of -60 deg C to 300 deg C.
Applications:
SIDER 309LMo joins stainless Types 304L, 316L and 410 to mild or low alloy steels. This wire also welds hardenable steels and provides a buffer layer prior to hard surfacing.
Dissimilar joint welds: mild steels and low-alloyed structural and Quenched-tempered (QT) steels, among themselves or among each other; unalloyed as well as low alloyed boiler or structural steels with stainless Cr, Cr-Ni and Cr-Ni-Mo steels; ferritic-austenitic joint welds in boiler and pressure vessel parts.
Weld Surfacing: for the first layer of corrosion resistant surfacing on P235GH, P265GH, S255N, P295GH, S355N - S500N; for the first layer of corrosion resistant weld surfacing on high temperature quenched and tempered fine grained steels.
