Description
Weld Star – A33 (ER 90S-B3) TIG Wire (3.2mm) 5kg
Weld Star – A33 TIG Wire is a low alloy, copper-coated wire designed with 2.25% Chromium (Cr) and 1% 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 elevated temperatures.
Features and Benefits:
- Heat Resistant: Designed for welding heat-resistant steels, making it ideal for high-temperature applications up to 600°C.
- High-Quality Welds: Produces high-quality welds suitable for pressure piping or boiler work.
- Corrosion Resistant: Offers high resistance to corrosion, particularly in challenging environments.
- 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.
- Chemical and Petrochemical Industries: Suitable for applications in the chemical and petrochemical sectors where high-temperature resistance is required.
Typical Base Materials:
10CrMo9-10, GS 17CrMoV5 11, 10CrSiMoV7, 12CrSiMo8, GS12CrMo9 10, 10CrSiMoV7, 10Cr V63, 12CrSiMo8 (Illustrative, not exhaustive list).
