Weld Star – A30 (ER 70S-A1) TIG Wire (2.4mm) 5kg
Features and Applications
A copper-coated heat-resisting wire containing 0.5% molybdenum.
Designed for welding low alloy creep-resistant steels that require a high tensile strength. The weld deposit is highly resistant to cold cracking. It is recommended for working temperatures of up to 500 degrees Celsius.
Typically used on creep steels for construction of steam boilers, pressure tanks, gas pipes, shipbuilding sector, petrochemical industry, heat exchangers, building of cranes, bridges, etc.
The green wire is produced using virgin raw materials sourced from specialized steel mills, which ensures consistent reliability and quality.
