Features
- General purpose DC+ electrode for mild and low alloy steels.
- Basic covering coating for stable arc performance and easy slag removal.
- Low diffusible hydrogen content (< 5.0 ml/100 g) for crack-resistant welds.
- Classified to AWS A5.1 (E7018) and EN ISO 2560-A (E 42 4 B 42 H5).
- Approved by ABS, BV, CE, DB, DNV, LR, UKCA and VdTÜV.
- High yield strength (445 MPa) and tensile strength (540 MPa) as welded.
- Excellent ductility with 28 % elongation in the as-welded condition.
- Charpy V-Notch impact toughness 70 J at − 40 °C.
- Typical weld metal analysis: C 0.04 %, Mn 1.19 %, Si 0.64 %.
- Deposition rate of 1.76 kg/h at 120–190 A for 4.0 × 450 mm electrodes.
- 22 electrodes per kg of weld metal (4.0 × 450 mm).
- Fusion time per electrode at 90 % Imax: 92 sec.
