Product Description
Designed on a highly alloyed core wire with a high purity lime/rutile flux coating that deposits high chromium duplex weld metal
with excellent resistance to corrosion and erosion. The microstructure of the as deposited weld contains 30% to 50% delta
ferrite – balance austenite. This electrode has a very stable arc, low spatter, easy strike and restrike, good slag detachability
and porosity free smooth welds. Mac Stain E122 is designed to weld the following alloys when no subsequent solution heat
treatment is applied to the weldment. ASTM A182 Grade F51, UNS S31803, DIN 1.4462, BSC Hyresist 22/5, Sandvik SAF
2205, Avesta 2205, Valourec VS22.
