The electrode can be used where resistance to pitting corrosive attack and resistance to stress corrosion cracking are required. The major application area includes, oil & gas industry, offshore platforms, petrochemical plants, mechanical & structural components demanding high strength together with high corrosion resistance.
1. Ensure the electrodes are dry. Re-dry the electrodes at 250-300°C for one hour.
2. Use stringer beads, short arc and smallest possible size, which helps in reducing the heat input.
