Arc Welding Service

CATEGORY

TYPE

Solid welding wire for dissimilar welding and buffer layers

APPLICATIONS

Buffer layers before hardfacing, dissimilar welding between steel and stainless steel, armor plate, exhaust systems (type 409, 304), high Manganese austenitic steel, heterogeneous welding, difficult to weld steels etc.

PROPERTIES

Corrosion resistance is equivalent to type 304, high mechanical properties and good weldability, work hardening and cold-tough to -110°C.
