OK 76.18

OK 76.18 is a basic DC stick electrode designed for welding creep‑resisting low‑alloy steels (1 % Cr, 0.5 % Mo). It delivers a stable arc with minimal spatter and produces weld metal resistant to cracking and porosity.

Key Features

• Basic covering for DC+(-) welding
• Low‑hydrogen (< 5 ml/100 g) for reduced cracking risk
• VacPac™ hermetically sealed packaging – dry electrodes straight from the pack
• Wide amperage range across multiple electrode diameters
