ER309LSi

Description:

Cromatig 309LSi deposits a 24% Cr / 13% Ni austenitic stainless steel weld metal with a nominal

ferrite content of FN 10. The relatively high alloy and ferrite levels enable the weld metal to tolerate

dilution from mild or low alloyed steels without hot cracking. The higher silicon content provides a

more fluid weld pool which may be preferred for certain welding applications.

Applications:

- Buffer layers on mild and low alloy steels prior to overlaying with MIG/TIG 308L.

- Joining of clad steels and dissimilar joints between stainless and mild or low alloy steels.

- Welding of similar composition, 309L type, stainless steels.

- Joining of ferritic-martensitic stainless steels.
