For Stainless Steels Alloys

LoTherme-477 produces fully austenitic in structure and possesses high strength, high ductility, good toughness, creep strength and resistance to scaling weld metal. It is characterized by a stable arc, which is easy to strike and re-strike. Easily removable slag, smooth finely rippled welds of radiographic quality.

LoTherme-477 is ideally suited for welding heat-resistant rolled steels. It is specially designed for welding of stainless steel AISI 310 to itself and to other steels, straight chromium stainless steels, dissimilar steels, including steels of relatively high hardenability, clad steels, carbon-molybdenum and chromium-molybdenum piping. Some of the typical applications include welding of annealing plants, hardening plants, steam boiler construction, the crude oil industry and the ceramic industry heat kiln anchors, exchanges, heat-treating pots and boxes, furnace parts, etc.

Ultimate Tensile Strength : 560 MPa

Elongation (L=4d) : 30%

Ensure the electrodes are dry. Re-dry the electrode at 250°C for one hour before use. Clean the weld area completely free of oil, grease, paint, rust or any other foreign matter. Use low current, short arc and stringer beads.
