Supercito 7018 S

Basic heavy coated electrode for producing tough and crack-free welded joints even on steels having a carbon content up to 0.40%.Weld metal recovery is approximately 115%. Good operating characteristics when positional welding. Weld metal has good toughness properties down to -50°C. Ultimate mechanical properties in 7018-1 group. Suitable for buffer layers.

• Ultra smooth finely rippled weld beads.
• Less than 2.5ml diffusible hydrogen level.
• Highest impact notch toughness in class (>90 J at -46°C typical).
• Superior reliability for the critical welding of C-Mn microlloyed & low alloy structural steels.
• Recommended for critical security welding applications.
