Welding filler metals

TR Stelloy 21 5kg 3.2x1000 mm

Sample image, your configuration may differ.

Description

  • Cobalt-based TIG welding rod
  • Good sliding properties, stamped
  • Very good resistance to corrosion, frictional wear and impact stress
  • Good toughness and insensitivity to thermal shocks and alternating stresses
  • Particularly suitable for high operating temperatures in conjunction with impact or shock loads
  • Temperature resistant up to max. 800°C
  • Fields of application:
    • Applications on components that are exposed to a combination of impact stress, abrasion, high pressure and corrosion at temperatures of up to 900°C, such as valve seats and guides for large water or high-pressure fittings, forging hammers, pump shafts, etc.
    • Hot work tools with alternating thermal loads, e.g. extruder screws, combustion engines, earth drills, etc.
