ToolTectic 6 NHSS Electrode

Electrode for wear-resistant coatings

ToolTectic 6 NHSS

ToolTectic 6 NHSS is a special electrode with a high-speed steel-based weld metal – MoCrWV alloyed. Good red hardness, cutting edge retention and tempering resistance. The tempering ensures 
ensures exceptional mechanical properties at the deposit, with remarkable red hardness and resistance to oxidation at high temperatures, making this electrode ideal for tool protection and die steel components. It can also be used in the manufacture of cutting tools when using medium-carbon or low-alloy steels.

  • Longer service life of welded parts.

  • Excellent red hardness and oxidation resistance at high temperatures.
  • High edge retention.
  • High mechanical strength.
  • Welding in all positions.
  • Quick repair of damaged tools.
  • Cost-effective process for manufacturing high-performance cutting tools made of low-cost steel.


Technical data
DIN EN 14700: E Fe4
AWS A5.13: E Fe5-B
Hardness: ~62 HRC

Applications
Punching, pressing, drawing and cutting tools; steel processing; hot and cold dressing tools; chisels, forging tools; coupling forks, valves, control cams, excavator grabs, mixer blades, screw conveyors.

Welding instructions
Preparation
Clean the weld area of scale and/or rust and remove grease.
Crack detection using dye penetrant. Prepare cracks by grinding to create a ‘U’ profile. Hold the electrode almost vertically. Preheat slowly according to the quality and heat treatment condition of the base material.

Welding parameters
Welding current: = (+) / ~
Amperage (A)
Ø 2.5 mm: 55– 70 A
