Weld Star – CrMo5 TIG Wire is a low alloy, copper-coated wire designed with 5% Chromium (Cr) and 0.5% Molybdenum (Mo) content. This wire is specifically formulated for welding heat-resistant steels and offers both high strength and corrosion resistance, especially in environments with hot hydrogen gas.

Features and Benefits

  • Heat Resistant: Designed for welding heat-resistant steels, making it ideal for high-temperature applications.
  • Corrosion Resistant: Offers high resistance to corrosion, particularly in challenging environments.
  • High Strength: Provides strong welds that can withstand demanding conditions.
  • Quality Production: Made with virgin raw materials sourced from specialized steel mills, ensuring consistent quality and reliability.

Common Applications

  • Power Plants: Used in pressure piping in steam power generating plants.
  • Boilers and Heat Exchangers: Ideal for welding boiler and heat exchanger tubes.
  • Oil Refineries: Suitable for applications in oil refineries where high-temperature resistance is required.
  • Chemical and Petrochemical Industries: Used in various applications in the chemical and petrochemical sectors.
