1% Ni low-alloy electrode, suitable for sour gas
Lincoln Electric Excalibur® 8018-C3 MR® (AWS E8018-C3 H4R) is a 1% nickel low-hydrogen electrode. It delivers a strong deposit that stays tough at -40 °C, ideal for pipeline repair, gas storage tanks and weathering steels. In 2.50 mm it is ideal for root passes and thin sections, with good puddle control.
Key advantages
- 1% Ni alloyed: up to 620 MPa tensile strength.
- Low-temperature toughness: up to 159 J Charpy impact at -40 °C.
- Sour gas service: pipeline and gas tank repair.
- MR coating: resists moisture pickup.
- Certified quality: ABS, TÜV and CWB approvals.
Applications
- Repair of cross-country oil and gas pipelines.
- Gas piping and storage tanks.
- Weathering steels.
- Shipbuilding.

Technician's tip: Lincoln's MR coating resists moisture pickup, but it is still a low-hydrogen electrode: once the can is open, keep it in a holding oven and avoid leaving it exposed during the shift.
