Corotherme (SPL) is a special electrode depositing a 0.5Cr - 0.7Ni - 0.5Cu weld metal ideally suited for welding weathering steels to resist high temperature atmospheric corrosion. Ideal for welding steels like Corten steels used in chemical, petrochemical and railway industries to resist atmospheric corrosion.
1. Ensure the electrodes are dry. Re-dry the electrodes at 250-300°C for one hour.
