Stainless steel repair electrode
Product description
Rutile-base electrode depositing a very low-carbon austenitic steel for joining Cr 23 – Ni 12 – Mo 2 stainless steels, as well as for welding dissimilar grades of steel, such as stainless steel to alloy or non-alloy steel.
Used as an undercoat prior to hardfacing on type 316 L steels and as an intermediate layer when welding clad type 316 L steels.
Universal maintenance repair electrode with ~20% high ferrite content.
Excellent resistance to cracking. High corrosion resistance. Smooth melting, good bead appearance, self-removing slag.
