4.0MM 312 Dissimilar Stainless Steel Arc Rods

A strong arc welding electrode for high strength and surface finishing for similar/equal steels or cast steels, for joint welding tensile unalloyed steels, tempered and tool steels, high manganese steels, spring steels and joints between dissimilar steels with high alloyed stainless steels.

For crack-proof tough inter-passes on hard surfacings and for abrasion resistant and warm hardened surfacings. The austenitic–ferritic weld metal is stainless & corrosion resistant. Due to enhanced delta–ferrite content, black/white joints are highly resistant against hot-cracking.
