Weldstar 312 5Kg Tig Filler Wire

Weldstar 312 Spec Sheet

Austenitic stainless steel wire originally designed to weld cast alloys of similar composition.

It gives a two-phase weld deposit with substantial percentages of ferrite in austenite matrix.

Ideal for welding dissimilar metals such as carbon steel to stainless steel, particularly those grades high in nickel.

Due to its high ferrite level, ER 312 is very adapted to heterogeneous welding, especially when one of the components is fully austenitic.

Good corrosion oxidation resistance at high temperature due to its high content of Cr.

Service temperatures should be below 420°C to prevent formation of secondary brittle phases.

Typically used on industrial furnaces, annealing chambers, fused salt treatment installations and boiler parts, as well as heat exchangers etc.
