SW 309 L Si 15kg/Spule 0.8mm

Sample image, your configuration may differ.

Description

  • High-alloy solid wire electrode, non-corroding
  • Layer-wound
  • Very good corrosion and scale resistance
  • Excellent welding properties (better seam appearance) due to higher Si content
  • Suitable for dissimilar joints and buffer layers
  • Heat and scale resistant up to approx. +950°C
  • For operating temperatures up to approx. +300°C
  • Fields of application:
  • Industrial furnaces and boiler parts, annealing chambers, heat exchangers, processing plants
