Description
Weld Star – ER 120S-G TIG Wire (2.4mm) 5kg
Weld Star – ER 120S-G TIG Wire is a copper-coated wire enriched with NiCrMo, specifically tailored for welding ultra-high tensile strength steels. This wire is particularly suitable for fine grain steels that exceed 890 MPa in yield strengths. With its high impact strength at low temperatures and exceptional plasticity of the weld deposit, it is versatile for a wide range of applications.
Features and Benefits:
- Ultra-High Tensile Strength: Designed for welding steels with yield strengths exceeding 890 MPa.
- Low-Temperature Performance: Offers high impact strength even at temperatures as low as -40°C.
- High-Quality Production: Made with virgin raw materials sourced from specialized steel mills, ensuring consistent reliability and quality.
- Versatility: Suitable for a myriad of applications from shipbuilding to railway and mining.
Common Applications:
- Construction: Used in the building of bridges, tanks, transport facilities, and more.
- Machinery: Ideal for lifting and handling machinery, cranes, and frames.
- Transportation: Finds usage in shipbuilding, railway, and other transport-related constructions.
- Mining: Suitable for mining-related structures.
