For Stainless Steels Alloys

LoTherme-464

Low heat input, special purpose stainless steel electrode for welding stainless steels and steels to resist scaling upto 1100°C.

Characteristics

LoTherme-464 is characterized by a stable arc, which is easy to strike and re-strike. Easily removable slag, smooth finely rippled welds of RADIOGRAPHIC quality. The weld metal is fully austenitic in structure and possesses high strength, high ductility, good toughness and creep strength. Resistance to scaling is retained up to 1100°C.

Applications

LoTherme-464 is ideally suited for welding of stainless steel AISI 310 to itself and to other steels, straight chromium stainless steels, dissimilar steels, including steels of relatively high harden ability, clad steels, carbon-molybdenum and chromium-molybdenum piping. Some of the typical applications include welding of heat kiln anchors, exchanges, heat-treating pots and boxes, furnace parts, etc.

Typical Mechanical Properties Of All Weld Metal

ULTIMATE TENSILE STRENGTH : 56 kgf/mm2

ELONGATION (L=4d) : 30 %

Welding Technique

Dry the electrode at 250°C for one hour before use. Keep the interpass temperature as low as possible by using current and low heat input. Use short arc and stringer beads.
