OK 76.28

OK 76.28 is a basic DC stick electrode designed for welding creep‑resisting low‑alloy steels (≈2.2 % Cr, 1.1 % Mo). It is vacuum‑packed in ESAB’s VacPac™ packaging to stay dry and ready for use straight from the bag.

Key Features

• VacPac™ hermetically sealed packaging keeps electrodes moisture‑free.
• Basic covering suitable for DC(+/-) welding.
• Low diffusible hydrogen (< 5 ml/100 g) for crack‑free welds.
• Wide amperage range for diameters 2.5‑6 mm.

Specifications

• Classifications: SFA/AWS A5.5 :E9018‑B3, EN ISO 3580‑A :E CrMo2 B 4 2 H5
• Approvals: BV C2M1 H5, CE EN 13479, UKCA EN 13479, VdTÜV 00971
• Welding Current: DC+(-)
• Diffusible Hydrogen: < 5 ml/100 g
• Alloy Type: Low alloyed (2.2 % Cr; 1.1 % Mo)
• Coating Type: Basic covering
• Deposition Data (example 4.0 × 450 mm): 130‑190 A, 28 V, 64 % efficiency, 88 s/fusion, 1.8 kg/h
