A rutile based, all position stainless steel Electrode for welding Duplex stainless steels.
CLASSIFICATION
: AWS/SFA-5.4: E 2209-16
DIN E 22 9 3 LR 23
DIN E 22 9 3 LR 23
CHARACTERISTICS :
Ratna 2093L is medium heavy coated, all position electrodes depositing “duplex” micro structure, consisting of a ferrite matrix, a stainless steel requirement of armour steel. Weld metal has excellent corrosion resistance especially to atmosphere, sea wear and weak acids.
APPLICATION :
- To join stainless to carbon steel, for depositing austenitic weld metal on higher carbon steel, armour steel etc.
- Weld metal deposited by electrodes combines increase tensile strength and resistance to pitting corrosion attack and to stress corrosion cracking for satisfaction services.
RE-DRY CONDITION :
Re-Dry the electrode at 250°C for 1 hrs before use.
