Basic coated electrode with nominal 0.5% Mo alloy resulting in improved elevated temperature performance over that of CMn steels. Typically used on vessels, pipe work where creep rupture strength and ductility is required.
Features and Applications
Basic-coated stick electrode
Welding of heat-resisting, Mo-alloyed, thin-walled and unalloyed steels used for construction of boilers and pipes
Weld metal is resistant to working temperatures from -50°C to +550°C Re-drying: 300-350°C min. 2h
Vacuumed packed electrodes
