Lincore® 55

Metal-Cored Submerged Arc (SAW)

Low Alloy steels designed for rebuilding of carbon or low alloy parts used in applications involving non-lubricated rolling or sliding metal-to-metal wear, and in applications with severe abrasion accompanied by low or moderate impact, works best in Metal-to-Earth applications.

DETAILS

Low Alloy steels designed for rebuilding of carbon or low alloy parts used in applications involving non-lubricated rolling or sliding metal-to-metal wear, and in applications with severe abrasion accompanied by low or moderate impact, works best in Metal-to-Earth applications.

Features

  • To be used on carbon steel, low alloy steel and manganese steel
  • Unlimited layers with proper preheat and interpass temperatures and procedures
  • Delivers a deposit which resists metal-to-metal rolling or sliding wear as well as mild abrasion

Typical Applications

  • Bark removing, Blade, Blower, Brake, Crane, Crush
  • Drag, Drive, Drum, Excavate, Extrusion, Hammer
  • Ingot, Kiln, Loader, Logging, Mill, Mine Car
  • Mix, Open Hearth, Plate, Power Generation, Rail, Roll
  • Shovel, Sinter, Teeth, Tractor, Wheel

Welding Positions

  • Flat/Horizontal

NOTES

Note
Cold parts should be warmed to at least 25°C (75°F). Higher preheat of 150 - 260°C (300 - 500°F) may be necessary on thick parts or heavy sections.
Interpass temperatures between 150°C (300°F) and 200°C (400°F) do not affect the hardness of Lincore® 55 significantly.
