MMA rutile flux coated 347 electrode on high purity 304L core wire. Ultramet 347 has all the benefits of an advanced rutile flux design, including all-positional fixed pipework welding with the 2.5/3.2mm diameter electrodes. Recovery is about 110% with respect to the core wire, and 65% with respect to the whole electrode.
Applications
Used to weld titanium and niobium stabilised 18/8 stainless steel types 321 and 347. Also suitable for unstabilised grades such as 304/304L. Service temperatures are typically -100°C to about 400°C. Applications are similar to 308L (B-30) and include food, brewery, pharmaceutical equipment, architectural and general fabrication, and nuclear engineering.
