LoTherme-514HD

High deposition electrode for welding Ni-Cr-Mo-W-Co alloys and for surfacing application.

CHARACTERSTICS

LoTherme-514HD is a high deposition electrode, developed to produce high nickel deposit containing carefully controlled quantities of Chromium, Molybdenum, Tungsten and Cobalt.

  • Retain hardness even at elevated temperatures.
  • Excellent heat resistance, strength and toughness up to about 1000°C.
  • High resistance to corrosion by most types of acids or their combinations.
  • Good thermal shock resistance.
Applications :

LoTherme-514 is ideally suited for welding Ni-Cr-Mo alloys to themselves, to other metals and for surfacing steel with Ni-Cr-Mo deposit. Applications in this category include valves, pumps, etc. LoTherme-514 is thus highly suited for hot working tools, e.g. shear blades, forging dies, punches, hot trimming dies, heating elements, etc.

Typical Mechanical Properties of All Weld Metal:

ULTIMATE TENSILE STRENGTH : 70 Kgf/mm2

ELONGATION (L=4d) : 28 %

WORK HARDENS UNDER IMPACT TO 400 BHN

Welding Technique :

Re-dry the electrode at 250-300 C for one hour before use. Use low current, short arc and stringer beads. Wherever possible weld in flat position.

Current Conditions : DC (+) / AC
