• Used to weld ½Cr-½Mo, 1Cr-½Mo, 1¼Cr-½Mo steels for elevated temperatures and corrosive service.
• These creep resistant steels are typically used in chemical industries for heat exchangers, boilers, piping and pressure vessels at service temperatures up to 1000°F.
• Careful control of preheat, interpass temperatures, and post heat is essential to avoid cracking.
• These electrodes are classified after post weld heat treatment.
• Special care must be used when using them in the as-welded condition due to high strength levels.
• For use with high pressure vessels, oil refining industries, steam pipes of boilers
• This wire is designed for welding of 1.25% Cr-0.5% Mo steel used for high pressure vessels, oil refining industries, steam pipes of boilers etc.
• It is a rutile type flux cored wire for all position welding.
