Features
- Low-alloyed (0.5% Mo) basic covered electrode for welding pressure vessel steels
- Suitable for DC+ and AC currents with excellent arc stability and runnability, even in inclined positions
- Hermetically sealed ESAB VacPac™ packaging protects electrodes from moisture; ready to use without re-baking
- Certified to AWS A5.5: E7018-A1 and EN ISO 3580-A: E Mo B 3 2 H5 classifications
- Diffusible hydrogen ≤5 ml/100 g ensures low-hydrogen welds
- Typical yield strength 460 MPa, tensile strength 560 MPa, and elongation 27% after PWHT
- Charpy V-notch impact value of 175 J at +20 °C following PWHT
- Deposition rate up to 1.8 kg/h at 140–200 A and 26 V on 4.0 × 450 mm electrodes
- Recommended preheat 125–200 °C for thicknesses over 12 mm and post-weld heat treatment at 580–630 °C for 30 min
- Optimized coating composition for low-current pipe welding applications
