Abracrom 312
Stainless electrode for repairing
Description & applications
Rutile-basic electrode with an austenitic-ferritic stainless steel deposit - adapted for welding dissimilar steels (stainless steels with low alloyed steels) and steels difficult to weld as tool steels, Mn steels, spring steels...- metal deposit highly resistant to cracks-suitable for buffer layers before hardfacing and for building up cutting tools - soft fusion- nice aspect of the beads- self releasing slag.
