Product Description

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.

Weld deposit highly resistant to cold cracking.

Recommended working temperatures of up to 500°C.

Typically used on creep steels for construction steam boilers, pressure tanks, gas pipes, shipbuilding sector, petrochemical industry, heat exchangers, building of cranes, bridges etc.

Green wire is produced using virgin raw materials sourced from specialised steel mills, which ensures consistent reliability and quality.
