Exaton 309/309L HF
309/309L HF welding wire is used for MIG/MAG welding. It is particularly suitable for overlay welding and joining dissimilar steels, for example austenitic stainless steels to low alloyed or non alloyed steels. It has excellent resistance to hot cracking due to its enhanced ferrite content.
