Low heat input, all position, Cr-Ni-Nb stabilized electrode.
LoTherme-453 produces Nb stabilized weld deposits with balance Cr-Ni ratio and controlled ferrite for excellent resistance to corrosion. The electrode is characterized by soft and stable arc, which is easy to strike and re-strike, finely rippled weld beads of radiographic quality and easily detachable slag.
LoTherme-453 is ideally suited for low heat input welding on AISI 301, 302, 304, 304L, 308, 308L, 321 and 347 stainless steel which are used in oil refining, chemical, paper pigments and paints, brewery, dairy and food processing industries. The welds have excellent resistance to carbide precipitation and the resultant inter-granular corrosion.
Ultimate Tensile Strength : 530 MPa
Elongation (L=4d) : 30 %
For best results, re-dry the electrodes at about 250°C for one hour before use. Clean Weld surface thoroughly free of any surface contamination. Use short arc and stringer bead technique.
