AWS A5.5: E7018–A1 | ISO 3580-A: EMoB 42 H5 | DIN EN 1599: EMoB42 | DIN 8575: EMo B10+
Creep-Resistant | 115% Recovery | Mo Steel Qualified
A moisture-resistant, low hydrogen electrode developed for boiler, pipe, and pressure vessel welding of creep-resistant steels containing 0.5% Mo and 0.5–1.0% Cr. Delivers reliable all-position welds with high arc stability, smooth bead profile, and strong performance both as-welded and after stress relieving. Suitable for high-temperature applications up to 525 °C. Trusted in fabricating cement kilns, chemical vessels, cast steel machinery, and other high-stress structures.
