Abracrom 312 VAC
Stainless steel repair electrode
Product description
Rutile-base electrode depositing austenitic-ferritic steel. Especially suitable for welding dissimilar steels (stainless steel with unalloyed steel), and materials considered difficult to weld, such as tool steels, manganese steels, cast steels, spring steels, gears, cylinder rods, etc.
The deposited metal is particularly resistant to cracking and is also suitable as an undercoat prior to hardfacing and for hardfacing sharp tools. Smooth melting, attractive bead appearance, self-removing slag.
