OK 76.16

OK 76.16 is a basic DC low‑hydrogen stick electrode designed for welding creep‑resisting steels (1.25 % Cr, 0.5 % Mo).

Key Features

• Basic covering provides low hydrogen content (< 4 ml/100 g).
• VacPac™ hermetically sealed packaging keeps electrodes dry for use straight from the pack.
• Suitable for DC+(-) welding current.
• Meets multiple classifications and approvals (SFA/AWS A5.5, EN ISO 3580‑A, CE, NAKS/HAKC, VdTÜV).
