Description
Weld Star – A15 (ER 70S-2) Wire (1.2mm) 15kg
Weld Star A15 (ER 70S-2) is a micro-alloyed steel wire that is triple de-oxidised with Titanium, Aluminum, and Zirconium. It is highly resistant to cold cracking, making it an excellent choice for welding low alloy creep-resistant steels. The wire is recommended for high-strength welding at temperatures of up to 500 degrees Celsius. It is precision layer wound, ensuring superior wire feeding characteristics and consistent reliability.
Features & Benefits:
- Cold Crack Resistance: Highly resistant to cold cracking, ensuring durable welds.
- High-Temperature Welding: Suitable for high-strength welding at temperatures up to 500°C.
- Triple De-Oxidised: Contains Titanium, Aluminum, and Zirconium for enhanced welding properties.
- Versatility: Ideal for use on greasy and oxidised surfaces, including galvanised steel.
- Low-Temperature Performance: Performs well at low temperatures.
- Superior Wire Feeding: Precision layer wound for consistent and reliable wire feeding.
- Quality Assurance: Green wire is produced using virgin raw materials from specialised steel mills, ensuring top-notch quality and reliability.
Common Applications:
- Tanks and containers
- Automotive industry
- Structural work
- Household appliances
- Pipelines
- Boilers
- Naval and petrochemical sectors
